WASHINGTON - US media identified the other woman as 37-year-old Jill Kelley, a "social liaison" to a Florida air force base who apparently had a longstanding friendship with Petraeus but no official status in the military.The FBI launched an inquiry after Kelley said she had received vicious emails from Gen Petraeus' biographer Paula Broadwell.The investigation revealed first that the emails had come from Broadwell and following an examination of her computer, it transpired that she had had an affair with Gen Petraeus. Politicians now want to know why they were not told about the affair sooner, with one even suggesting a cover-up.David Petraeus, the 60-year-old four-star general, described his behaviour as "unacceptable" for the CIA's leader.Fresh reports piled pressure on FBI and CIA officials to explain the circumstances and timing of an investigation that ended the storied career of spy chief David Petraeus just three days after President Barack Obama's re-election. Petraeus resigned as head of the Central Intelligence Agency last week after admitting an extramarital affair, sparking concerns of a security breach and sending shockwaves around Washington.A leading Republican on Sunday questioned why, if there were serious concerns about comprised intelligence, it had taken several months for the FBI to finally notify the Obama administration. "It just doesn't add up," Peter King, the top Republican on the House Homeland Security Committee, told CNN. "I have real questions about this. I think a timeline has to be looked at and analyzed to see what happened."The questions were expected to multiply following a New York Times report on Monday that high-level officials at the Federal Bureau of Investigation and the Justice Department had known about Petraeus' affair since late summer, but did not notify anybody outside of the agencies until last week.The law requires that the Senate and House intelligence committees be kept "fully and currently informed" of what the CIA and FBI are doing. And Senate Intelligence Committee Chairman Dianne Feinstein made it clear that she was not pleased.Appearing on the "Fox News Sunday" television show, she said she wanted to know why the FBI didn't notify the intelligence committees sooner."We should have been told," Feinstein remarked.The US government is closed on Monday as part of the Veterans Day holiday. But on Tuesday, when the government reopens, senior FBI and CIA officials were scheduled to meet with leading members of Congress to bring them up to date about details of the probe. It has emerged that the woman he was having an affair with is Paula Broadwell, a 40-year-old former Army major, granted unprecedented access to the general as she co-authored his best-selling biography.
