Paula Broadwell Revealed As Mistress In Petraeus Affair, Wrote Biography of General, Spoke About Him on "Daily Show" in January (Video)

The mistress of CIA Director David Petraeus was revealed on Friday as journalist and Petraeus biographer Paula Broadwell.

Petraeus resigned yesterday, after admitting to the extramarital affair.

Broadwell is the author of “All In: The Education of General David Petraeus,” which was released in January of this year.

Broadwell visited Afghanistan six times to interview Petraeus, spending a total of three months embedded in a combat zone with the general.

Here she is on the Daily Show with Jon Stewart saying Petraeus isn’t a “long-term strategic thinker.”

Petraeus told President Obama of the affair on Thursday and tendered his resignation. Obama accepted on Friday, saying, "By any measure, through his lifetime of service, David Petraeus has made our country safer and stronger," in a statement. "Going forward, my thoughts and prayers are with Dave and Holly Petraeus, who have done so much to help military families through her own work. I wish them the very best at this difficult time."

Petraeus also released a statement, explaining his decision to resign and apologizing for his behavior.

"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 led the wars in Iraq and Afghanistan in the later years of the presidency of George W. Bush. He oversaw the "surge" in Iraq, and influx of American troops that quelled much of the insurgency and paved the way for a removal of troops under the Obama administration.

After Iraq, Petraeus moved to Afghanistan to try to repeat the maneuver, but he was unsuccessful. In 2011, Petraeus moved to the CIA, replacing Leon Panetta, who took a new post at the Defense Department.

Senator Dianne Feinstein of California, chair of the Senate Intelligence Committee, told NBC News, "I would have stood up for him. I wanted him to continue. He was good, he loved the work, and he had a command of intelligence issues second to none."

Republican Representaive Peter King of New York, chairman of the House Committee on Homeland Security, said, "General Petraeus is one of America's most outstanding and distinguished military leaders and a true American patriot."

And former presidential candidate and Senator John McCain said, "General David Petraeus will stand in the ranks of America's greatest military heroes."
