Congress wants answers on Petraeus affair

WASHINGTON (AP) — Members of Congress said Sunday they want to know more details about the FBI investigation that revealed an extramarital affair between ex-CIA Director David Petraeus and his biographer, questioning when the retired general popped up in the FBI inquiry, whether national security was compromised and why they weren't told sooner.

"We received no advanced notice. It was like a lightning bolt," said Democratic Sen. Dianne Feinstein of California, who heads the Senate Intelligence Committee.

The FBI was investigating harassing emails sent by Petraeus biographer and girlfriend Paula Broadwell to a second woman. That probe of Broadwell's emails revealed the affair between Broadwell and Petraeus. The FBI contacted Petraeus and other intelligence officials, and Director of National Intelligence James Clapper asked Petraeus to resign.

A senior U.S. military official identified the second woman as Jill Kelley, 37, who lives in Tampa, Fla., and serves as an unpaid social liaison to MacDill Air Force Base in Tampa, where the military's Central Command and Special Operations Command are located.

Staffers for Petraeus said Kelley and her husband were regular guests at events he held at Central Command headquarters.

In a statement Sunday evening, Kelley and her husband, Scott, said: "We and our family have been friends with Gen. Petraeus and his family for over five years. We respect his and his family's privacy and want the same for us and our three children."

A U.S. official said the coalition countries represented at Central Command gave Kelley an appreciation certificate on which she was referred to as an "honorary ambassador" to the coalition, but she has no official status and is not employed by the U.S. government.

The official, speaking on condition of anonymity because he wasn't authorized to discuss the case publicly, said Kelley is known to drop the "honorary" part and refer to herself as an ambassador.

The military official, who spoke on condition of anonymity because he was not authorized to publicly discuss the investigation, said Kelley had received harassing emails from Broadwell, which led the FBI to examine her email account and eventually discover her relationship with Petraeus.

A former associate of Petraeus confirmed the target of the emails was Kelley, but said there was no affair between the two, speaking on condition of anonymity to discuss the retired general's private life. The associate, who has been in touch with Petraeus since his resignation, says Kelley and her husband were longtime friends of Petraeus and wife, Holly.

Attempts to reach Kelley were not immediately successful. Broadwell did not return phone calls or emails.

Petraeus resigned while lawmakers still had questions about the Sept. 11 attack on the U.S. Consulate and CIA base in Benghazi, Libya, that killed four Americans, including U.S. Ambassador Chris Stevens. Lawmakers said it's possible that Petraeus will still be asked to appear on Capitol Hill to testify about what he knew about the U.S. response to that incident.

Rep. Peter King, chairman of the House Homeland Security Committee, said the circumstances of the FBI probe smacked of a cover-up by the White House.

"It seems this (the investigation) has been going on for several months and, yet, now it appears that they're saying that the FBI didn't realize until Election Day that General Petraeus was involved. It just doesn't add up," said King, R-N.Y.

Petraeus, 60, quit Friday after acknowledging an extramarital relationship. He has been married 38 years to Holly Petraeus, with whom he has two adult children, including a son who led an infantry platoon in Afghanistan as an Army lieutenant.

Broadwell, a 40-year-old graduate of the U.S. Military Academy and an Army Reserve officer, is married with two young sons.

Petraeus' affair with Broadwell will be the subject of meetings Wednesday involving congressional intelligence committee leaders, FBI deputy director Sean Joyce and CIA deputy director Michael Morell.

Petraeus had been scheduled to appear before the committees on Thursday to testify on the attack in Benghazi. Republicans and some Democrats have questioned the U.S. response and protection of diplomats stationed overseas.

Morell was expected to testify in place of Petraeus, and lawmakers said he should have the answers to their questions. But Feinstein and others didn't rule out the possibility that Congress will compel Petraeus to testify about Benghazi at a later date, even though he's relinquished his job.

"I don't see how in the world you can find out what happened in Benghazi before, during and after the attack if General Petraeus doesn't testify," said Sen. Lindsey Graham, R-S.C.

Graham, who is a member of the Senate Armed Services Committee, wants to create a joint congressional committee to investigate the U.S. response to that attack.

Feinstein said she first learned of Petraeus' affair from the media late last week, and confirmed it in a phone call Friday with Petraeus. She eventually was briefed by the FBI and said so far there was no indication that national security was breached.

Still, Feinstein called the news "a heartbreak" for her personally and U.S. intelligence operations, and said she didn't understand why the FBI didn't give her a heads up as soon as Petraeus' name emerged in the investigation.

"We are very much able to keep things in a classified setting," she said. "At least if you know, you can begin to think and then to plan. And, of course, we have not had that opportunity."

Clapper was told by the Justice Department of the Petraeus investigation at about 5 p.m. on Election Day, and then called Petraeus and urged him to resign, according to a senior U.S. intelligence official who spoke on condition of anonymity because he was not authorized to discuss the investigation publicly.

FBI officials say the committees weren't informed until Friday, one official said, because the matter started as a criminal investigation into harassing emails sent by Broadwell to another woman.

Concerned that the emails he exchanged with Broadwell raised the possibility of a security breach, the FBI brought the matter up with Petraeus directly, according to the official, who spoke on condition of anonymity because he was not authorized to publicly discuss the investigation.

Petraeus decided to quit, though he was breaking no laws by having an affair, officials said.

Feinstein said she has not been told the precise relationship between Petraeus and the woman who reported the harassing emails to the FBI.

Georgia Sen. Saxby Chambliss, the top Republican on the Senate intelligence committee, called Petraeus "a great leader" who did right by stepping down and still deserves the nation's gratitude. He also didn't rule out calling Petraeus to testify on Benghazi at some point.

"He's trying to put his life back together right now and that's what he needs to focus on," Chambliss said.

King appeared on CNN's "State of the Union." Feinstein was on "Fox News Sunday," Graham spoke on CBS' "Face the Nation," and Chambliss was interviewed on ABC's "This Week."

Landmines kill 9 civilians in Afghanistan

KABUL, Afghanistan (AP) — Officials say landmines have killed nine civilians in separate incidents in eastern and southern Afghanistan.

Youqib Khan, who is deputy police chief for the eastern Khost province, said three men, two women and a baby died when their vehicle ran over a mine as they were returning home from hospital on Sunday morning.

In the south, three civilians were killed when their vehicle detonated a landmine Sunday on the road between Helmand and Kandahar provinces, a government statement said.

The United Nations says homemade bombs continue to be the deadliest weapon for civilians in the war.

Meanwhile, a U.S. soldier was killed by an improvised explosive device in southern Afghanistan on Saturday, a military statement said. It did not elaborate.

War photography exhibit debuts in Houston museum

HOUSTON (AP) — It was a moment Nina Berman did not expect to capture when she entered an Illinois wedding studio in 2006. She knew Tyler Ziegel had been horribly injured, his face mutilated beyond recognition by a suicide bombing in the Iraq War. She knew he was marrying his pretty high school sweetheart, perfect in a white, voluminous dress.

It was their expressions that were surprising.

"People don't think this war has any impact on Americans? Well here it is," Berman says of the image of a somber bride staring blankly, unsmiling at the camera, her war-ravaged groom alongside her, his head down.

"This was even more shocking because we're used to this kind of over-the-top joy that feels a little put on, and then you see this picture where they look like survivors of something really serious," Berman added.

The photograph that won a first place prize in the World Press Photos Award contest will stand out from other battlefield images in an exhibit "WAR/PHOTOGRAPHY: Images of Armed Conflict and Its Aftermath" that debuts Sunday — Veterans Day — in the Houston Museum of Fine Arts. From there, the exhibit will travel to The Annenberg Space for Photography in Los Angeles, the Corcoran Gallery of Art in Washington and The Brooklyn Museum in Brooklyn, N.Y.

The exhibit was painstakingly built by co-curators Anne Wilkes Tucker and Will Michels after the museum purchased a print of the famous picture of the raising of the flag at Iwo Jima, taken Feb. 23, 1945, by Associated Press photographer Joe Rosenthal. The curators decided the museum didn't have enough conflict photos, Tucker said, and in 2004, the pair began traveling around the country and the world in search of pictures.

Over nearly eight years and after viewing more than 1 million pictures, Tucker and Michels created an exhibit that includes 480 objects, including photo albums, original magazines and old cameras, by 280 photographers from 26 countries.

Some are well-known — such as the Rosenthal's picture and another AP photograph, of a naked girl running from a napalm attack during the Vietnam War taken in 1972 by Huynh Cong "Nick" Ut. Others, such as the Incinerated Iraqi, of a man's burned body seen through the shattered windshield of his car, will be new to most viewers.

"The point of all the photographs is that when a conflict occurs, it lingers," Tucker said.

The pictures hang on stark gray walls, and some are in small rooms with warning signs at the entrance designed to allow visitors to decide whether they want to view images that can be brutal in their honesty.

"It's something that we did to that man. Americans did it, we did it intentionally and it's a haunting picture," Michels said of the image of the burned Iraqi that hangs inside one of the rooms.

In some images, such as Don McCullin's picture of a U.S. Marine throwing a grenade at a North Vietnamese soldier in Hue, it is clear the photographer was in danger when immortalizing the moment. Looking at his image, McCullin recalled deciding to travel to Hue instead of Khe Sahn, as he had initially planned.

"It was the best decision I ever made," he said, smiling slightly as he looked at the picture, explaining that he took a risk by standing behind the Marine.

"This hand took a bullet, shattered it. It looked like a cauliflower," he said, pointing to the still-upraised hand that threw the grenade. "So the people he was trying to kill were trying to kill him."

McCullin, who worked at that time for The Sunday Times in London, has covered conflicts all over the world, from Lebanon and Israel to Biafra. Now 77, McCullin says he wonders, still, whether the hundreds of photos he's taken have been worthwhile. At times, he said, he lost faith in what he was doing because when one war ends, another begins.

Yet he believes journalists and photographers must never stop telling about the "waste of man in war."

"After seeing so much of it, I'm tired of thinking, 'Why aren't the people who rule our lives ... getting it?' " McCullin said, adding that he'd like to drag them all into the exhibit for an hour.

Berman didn't see the conflicts unfold. Instead, she waited for the wounded to come home, seeking to tell a story about war's aftermath.

Her project on the wounded developed in 2003. The Iraq War was at its height, and there was still no database, she said, to find names of wounded warriors returning home. So she scoured local newspapers on the Internet.

In 2004 she published a book called "Purple Hearts" that includes photographs taken over nine months of 20 different people. All were photographed at home, not in hospitals where, she said, "there's this expectation that this will all work out fine."

The curators, meanwhile, chose to tell the story objectively — refusing through the images they chose or the exhibit they prepared to take a pro- or anti-war stance, a decision that has invited criticism and sparked debate.

And maybe, that is the point.

Malaria vaccine a letdown for infants

LONDON (AP) — An experimental malaria vaccine once thought promising is turning out to be a disappointment, with a new study showing it is only about 30 percent effective at protecting infants from the killer disease.

That is a significant drop from a study last year done in slightly older children, which suggested the vaccine cut the malaria risk by about half — though that is still far below the protection provided from most vaccines. According to details released on Friday, the three-shot regimen reduced malaria cases by about 30 percent in infants aged 6 to 12 weeks, the target age for immunization.

Dr. Jennifer Cohn, a medical coordinator at Doctors Without Borders, described the vaccine's protection levels as "unacceptably low." She was not linked to the study.

Scientists have been working for decades to develop a malaria vaccine, a complicated endeavor since the disease is caused by five different species of parasites. There has never been an effective vaccine against a parasite. Worldwide, there are several dozen malaria vaccine candidates being researched.

In 2006, a group of experts led by the World Health Organization said a malaria vaccine should cut the risk of severe disease and death by at least half and should last longer than one year. Malaria is spread by mosquitoes and kills more than 650,000 people every year, mostly young children and pregnant women in Africa. Without a vaccine, officials have focused on distributing insecticide-treated bed nets, spraying homes with pesticides and ensuring access to good medicines.

In the new study, scientists found babies who got three doses of the vaccine had about 30 percent fewer cases of malaria than those who didn't get immunized. The research included more than 6,500 infants in Africa. Experts also found the vaccine reduced the amount of severe malaria by about 26 percent, up to 14 months after the babies were immunized.

Scientists said they needed to analyze the data further to understand why the vaccine may be working differently in different regions. For example, babies born in areas with high levels of malaria might inherit some antibodies from their mothers which could interfere with any vaccination.

"Maybe we should be thinking of a first-generation vaccine that is targeted only for certain children," said Dr. Salim Abdulla of the Ifakara Health Institute in Tanzania, one of the study investigators.

Results were presented at a conference in South Africa on Friday and released online by the New England Journal of Medicine. The study is scheduled to continue until 2014 and is being paid for by GlaxoSmithKline and the PATH Malaria Vaccine Initiative.

"The results look bad now, but they will probably be worse later," said Adrian Hill of Oxford University, who is developing a competing malaria vaccine. He noted the study showed the Glaxo vaccine lost its potency after several months. Hill said the vaccine might be a hard sell, compared to other vaccines like those for meningitis and pneumococcal disease — which are both effective and cheap.

"If it turns out to have a clear 30 percent efficacy, it is probably not worth it to implement this in Africa on a large scale," said Genton Blaise, a malaria expert at the Swiss Tropical and Public Health Institute in Basel, who also sits on a WHO advisory board.

Eleanor Riley of the London School of Hygiene and Tropical Medicine, said the vaccine might be useful if used together with other strategies, like bed nets. She was involved in an earlier study of the vaccine and had hoped for better results. "We're all a bit frustrated that it has proven so hard to make a malaria vaccine," she said. "The question is how much money are the funders willing to keep throwing at it."

Glaxo first developed the vaccine in 1987 and has invested $300 million in it so far.

WHO said it couldn't comment on the incomplete results and would wait until the trial was finished before drawing any conclusions.

Sick, frail struggle most in storm's aftermath

NEW YORK (AP) — Some of society's most vulnerable people — the elderly, the disabled and the chronically ill — have been pushed to the brink in the powerless, flood-ravaged neighborhoods struggling to recover from Superstorm Sandy.

The storm didn't just knock out electricity and destroy property when it came ashore in places like the Far Rockaway section of Queens. It disrupted the fragile support networks that allowed the neighborhood's frailest residents to get by.

Here, the catastrophe has closed pharmacies, kept home care aids from getting to elderly clients and made getting around in a wheelchair impossible. The city has recorded at least two deaths of older men in darkened buildings.

For some living in the disaster zone, it has all been too much.

When a team of medics and National Guardsmen turned up at Sheila Goldberg's apartment tower in Far Rockaway on Friday to check on the well-being of residents, floor by floor, the 75-year-old burst into tears and begged for help caring for her 85-year-old husband.

"This is a blessing. I'm at my wit's end," she said, sobbing.

Her husband, Irwin, has a pacemaker, wears a colostomy bag and needs her help to do almost everything. When the power was on, Goldberg said, "I could take care of him by myself and survive." But for days, the building had no heat or electricity. There were no open stores to buy food. Until the end of the week, there was no water or elevators either, meaning residents like the Goldbergs, on the 25th floor, had to cart water up the steps themselves just to flush the toilet. A bad stench permeates much of the building.

"I'm running out of my blood pressure medication. We're both going to drop dead in this apartment," Sheila said. The medical team said it would make arrangements to transfer Irwin to a medical facility, at least temporarily.

City and federal officials, and a growing army of volunteers, are trying hard to make sure families like that don't fall into despair. Their efforts come alongside relief workers, donations, volunteers and demolition crews who flocked to New York and New Jersey in recent days to assist in the massive cleanup. The region took a few more steps to move past the storm Saturday, when power was restored for many more and gas rationing eased some of the clogged lines at stations in New York.

Paramedics from all over the country, including the ones that found the Goldbergs, fanned out across the Rockaways this weekend to check on shut-ins and anyone else who might need help.

The idea was to find people who "sheltered in place" during the storm, who might need assistance, said Nancy Clark, an assistant commissioner in the city's health department.

The going was slow. In their first three hours, the teams had gone through five high-rise towers. Several people were taken to the hospital. Others were hooked up with water, food, blankets or needed prescription medications.

Two floors below the Goldbergs, medics from South Carolina found Daisy Nixon, 70, slumped in a chair under a pile of blankets. A diabetic and a victim of two strokes, she was suffering from an untreated dislocated shoulder injured before the storm. Nate Thompson, an EMT, checked her blood glucose levels and found them troublingly high.

"It's been cold. Lord, have mercy," Nixon said. She said she was also having trouble breathing at night. When Thompson said he would get her an ambulance, Nixon was overjoyed.

"Can I kiss you? Don't you walk away from me," she said, and planted a smooch on his cheek.

Another neighborhood resident, Joseph Williams, said that the home care aide who normally helps look after his 27-year-old son, who has cerebral palsy and needs a wheelchair, hasn't been able to visit since the storm. After days of trying to take care of him himself, in a flooded high-rise with no utilities, Williams gave up and carried him down seven flights, so he could be evacuated to Brooklyn.

Yet, there were rays of hope amid the gloom. In Newark, N.J., an Amtrak train arrived pulling a box car filled with donations from New Orleans.

Fuel lines in the region remained long, but were only a shade of the nightmare they had been in recent days. Some gas stations on Staten Island had 20 cars in line Saturday afternoon.

In Staten Island's waterlogged New Dorp section, volunteers walked in knots, often carrying shovels and pails with the price tags still on them. A Boy Scout troop served hot dogs and grilled cheese. People pushed grocery carts filled with food and bottled water. On one sidewalk, a generator was hooked up to a popcorn maker, spilling a fresh batch into a bowl.

Mandie Collins and Mary Lou Sabatini, from the West Brighton neighborhood of Staten Island, cooked a turkey and ham, and walked door to door with coolers offering sandwiches.

"It's surreal," Collins said. "I lived down the block before. I passed by my old apartment and it's gone."

Utility companies have made progress restoring power. Most service was expected to be restored in New Jersey over the weekend, and the utility that serves New York City and suburban Westchester County said it has restored electricity to about 99 percent of the 1 million homes and businesses that lost power in the storm and a subsequent nor'easter, though that percentage doesn't count tens of thousands of homes the utility says are too damaged to receive power.

Power problems remained unresolved on New York's Long Island, where about 300 people staged an angry protest at an office of the beleaguered Long Island Power Authority. About 130,000 of its customers still didn't have power Saturday, LIPA said.

Amid the drudgery and heartbreak of cleanup came one special moment for Joanne McClenin, who had 5 feet of water in her Staten Island home.

On Wednesday, her husband returned to their house to find someone had returned Joanne's 1930 baptism certificate from St. Anthony's Church in Manhattan. It had a smudge of mud on it.

The certificate had been stored in a file cabinet of her late parents' belongings, stored in a shed in their yard. The water from Sandy swept it away.

"It felt like my father was watching me," she said.

27 inmates killed in Sri Lanka prison shootout

COLOMBO, Sri Lanka (AP) — A shootout between rioting prisoners and security forces at a prison in Sri Lanka's capital killed at least 27 inmates, while police said Saturday that they arrested five prisoners who had managed to escape and were searching for others.

Another 42 people were wounded in the clashes Friday between inmates and army and police commandos that broke out after the rioting prisoners broke into the armory and briefly took control of at least part of the Welikada prison in Colombo. The situation at the prison had returned to normal by Saturday morning.

"The prison is now totally under our control," said Sri Lanka's Commissioner General of Prisons P.W. Kodippili.

Dr. Anil Jasinghe, director of the Colombo National Hospital, said the bodies of 16 inmates were at his hospital.

Kodippili said that security forces had found the bodies of 11 other inmates inside the prison premises and that the total number of deaths stood at 27.

Twenty-three inmates who were injured in the clash were receiving treatment at the hospital, Jasinghe said. Thirteen police officers, four soldiers, a prison guard and a passer-by also were being treated there, most of them with gunshot wounds.

Police spokesman Prishantha Jayakody said authorities recaptured five inmates who had escaped from the prison, which was the site of another riot earlier this year.

Kodippili declined to say how many inmates may have escaped, but he said search operations were under way to find others who may have fled.

Jayakody said the fighting began when police commandos went to the prison to conduct a search and were attacked by inmates hurling stones. He declined to provide more information. Officials often conduct raids for narcotics and communication devices.

An Associated Press photographer saw prisoners waving rifles atop the prison's roof Friday night.

Other prisoners piled into a three-wheeled vehicle and began driving toward a main city road before security forces outside the prison opened fire. The vehicle stopped, and three unmoving bodies could be seen.

Dozens of security officers then entered the prison, and volleys of gunfire rang out. Prisoners could be heard screaming, "Stop shooting!"

Army troops were called in later to help control the situation.

Kodippili said the inmates had broken into the prison's two armories during the riot and taken weapons stored there. The inmates opened fire at police commandos, who shot back.

He said that security forces had so far recovered 76 weapons taken by the prisoners and that six more weapons were still missing.

A clash between inmates and guards at the same prison last January wounded 28 people. Those prisoners were protesting the authorities' move to curtail drug smuggling into the facility.

China derides U.S. “Cold War mentality” towards telecoms firm Huawei

BEIJING (Reuters) – The United States is exhibiting a “Cold War mentality” with its fears that Chinese telecommunications equipment manufacturer Huawei poses a security risk because of its ties to the Communist Party, China‘s commerce minister said on Saturday.

The U.S. House of Representatives’ Intelligence Committee warned last month that Beijing could use equipment made by Huawei, the world’s second-largest maker of routers and other telecom gear, as well as rival Chinese manufacturer ZTE, the fifth largest, for spying.

The report cited the presence of a Communist Party cell in the companies’ management structure as part of the reason for concern.

The state role in business prompted a U.S. congressional advisory panel to complain this week that Chinese investment in the United States had created a “potential Trojan horse”.

“Can you imagine if China started asking U.S. companies coming to China what their relationship was with the Democratic or Republican parties? It would be a mess,” Commerce Minister Chen Deming, himself a Communist Party member, told reporters on the sidelines of the 18th Party Congress, which will usher in a new generation of leaders.

“If you see me as a Trojan horse, how should I view you? By this logic, if the Americans turned it around, they would see that it’s not in their interest to think this way.”

All Chinese state-owned enterprises and a growing number of private Chinese firms have a Communist Party secretary at the top of their management structure. In most cases, the top management are themselves party members.

Neither Huawei nor ZTE is state-owned. Huawei is owned by its employees and ZTE by different institutions.

Suspicions of Huawei are partly tied to its founder, Ren Zhengfei, a former People’s Liberation Army officer. Huawei denies any links with the Chinese military and says it is a purely commercial enterprise.

The Commerce Ministry China last month dismissed the U.S. suspicions as groundless.

“This report by the relevant committee of the U.S. Congress, based on subjective suspicions, no solid foundation and on the grounds of national security, has made groundless accusations against China,” spokesman Shen Danyang said.

Madonna fan guilty in NYC resisting arrest trial

NEW YORK (AP) — A former firefighter with a crush on Madonna has been convicted of resisting arrest outside her former New York City apartment building as he spray-painted poster boards with love notes.

A jury delivered its verdict Friday in Robert Linhart's trial. He could face up to a year in jail.

Defense lawyer Lawrence LaBrew tells the New York Post (http://bit.ly/ZgI4jl) that Linhart will appeal.

Linhart was arrested in September 2010. Police say he parked his SUV outside the singer's Manhattan apartment, laid out a tarp and wrote out such messages as "Madonna, I need you."

Jurors told the Post they felt it was fine for Linhart to express himself to the Material Girl. But they said they believed police testimony that he resisted arrest by flailing his arms.

How 'poor judgment' felled military star Petraeus

WASHINGTON (Reuters) - David Petraeus was a star on the battlefield, commanding the Iraq and Afghanistan wars, but was undone by "poor judgment" in engaging in an extramarital affair that led to his downfall as CIA director.

Just two days after his 60th birthday, Petraeus stepped down from the spy agency where he had held the top office since September 6, 2011.

"After being married for over 37 years, I showed extremely poor judgment by engaging in an extramarital affair. Such behavior is unacceptable, both as a husband and as the leader of an organization such as ours. This afternoon, the President graciously accepted my resignation," Petraeus told the shadow warriors he commanded at CIA.

It was a stunning downfall for a revered military man who was seen as one of the top American leaders of his generation and was once considered a potential contender for the White House.

Petraeus was credited with pulling Iraq from the brink of all-out civil war and for battlefield successes in Afghanistan after overseeing a surge of 30,000 troops ordered by President Barack Obama in late 2009. He became known for counter-insurgency strategies that were seen as gaining ground against the Taliban in Afghanistan.

"I don't think he was professionally overrated. His were genuine accomplishments," said James Carafano, a war historian with the conservative Heritage Foundation think tank.

At the time of his nomination to the CIA post, some Washington insiders had said the White House wanted to find a prominent position for Petraeus to ensure he would not be recruited by Republicans as a challenger to the 2012 Obama-Biden ticket.

When he was nominated to lead the CIA there were some concerns in intelligence circles that the high-profile four-star Army general might not be able to lead from the shadows as appropriate for a spy chief.

But once he took over the head office at the U.S. spy agency, Petraeus kept a decidedly low public profile.

Senate Intelligence Committee Chairman Dianne Feinstein, a Democrat, expressed regret about the resignation of "one of America's best and brightest" and said it was an "enormous loss" for the country.

"At CIA, Director Petraeus gave the agency leadership, stature, prestige and credibility both at home and abroad. On a personal level, I found his command of intelligence issues second to none," she said.

RESIGNATION ACCEPTED

After accepting his resignation about a year-and-a-half after nominating Petraeus to the CIA post, Obama said: "By any measure, he was one of the outstanding General officers of his generation, helping our military adapt to new challenges, and leading our men and women in uniform through a remarkable period of service in Iraq and Afghanistan, where he helped our nation put those wars on a path to a responsible end."

Earlier this week, in a Newsweek article entitled "General David Petraeus's Rules for Living," he listed 12 lessons for leadership. Number 5 was: "We all will make mistakes. The key is to recognize them and admit them, to learn from them, and to take off the rear­ view mirrors - drive on and avoid making them again."

In 2010 Petraeus stepped into the breach as the new commander of U.S. forces in Afghanistan to replace General Stanley McChrystal who was fired by Obama in a scandal over an article in which McChrystal and his aides made mocking comments about the president and some of his top advisers.

In 2009 Petraeus was diagnosed with early-stage prostate cancer and underwent radiation treatment. The media-friendly general joked at that time at a Washington event that reporters were only gathered "to see if the guy is still alive."

Petraeus, born in Cornwall, New York, lives in Virginia with his wife Holly. They have two grown children, a son who was an Army Ranger who served in Afghanistan, and a daughter.

Petraeus's wife, Holly, is an activist and volunteer who champions military families, and she continued that work after her husband retired from the military and moved to the CIA.

She currently is assistant director of the office of servicemember affairs at the Consumer Financial Protection Bureau, where she tries to keep unscrupulous lenders from taking advantage of military personnel. The bureau was championed by Harvard law professor Elizabeth Warren, who was elected to the Senate from Massachusetts this week.

Holly Petraeus is the daughter of four-star General William Knowlton, who was superintendent of the U.S. Military Academy at West Point when Petraeus was a cadet.

She briefed the press at the Pentagon on her efforts recently and was introduced by Defense Secretary Leon Panetta, who called her "a true friend of the Department of Defense and a dedicated member of our military family."

Petraeus has four Defense Distinguished Service Medal awards, three Distinguished Service Medal awards, the Bronze Star Medal for valor, and the State Department Distinguished Service Award.

He has a doctorate in international relations from Princeton University.
