FBI Investigating Agent Who Launched Petraeus Case He was sidelined after becoming obsessed with case By Rob Quinn, Newser Staff Posted Nov 13, 2012 4:49 AM CST 5 comments Comments FBI agents carry boxes and a computer from the home of Paula Broadwell Monday night. (AP Photo/Chuck Burton) (Newser) – David Petraeus' affair scandal is getting messier by the day: The federal agent who launched the investigation that led to the CIA director's downfall is himself being investigated by the FBI over his conduct, officials tell the Wall Street Journal. The agent is a friend of Jill Kelley, the Tampa woman who complained about threatening emails from Petraeus' mistress Paula Broadwell—and who has now been linked to the American commander in Afghanistan. Officials say they barred the agent from the investigation amid fears that he had become obsessed with it and had become personally involved. Even before the investigation began, the agent allegedly sent shirtless photos of himself to Kelley, who is married. After the agent was sidelined, officials say, he contacted a Republican member of Congress (perhaps Eric Cantor?) because he feared the FBI was going to sweep the investigation under the rug. Other news in the case that keeps on giving: FBI agents searched Broadwell's home in North Carolina last night, Reuters reports. Agents were seen leaving the house carrying evidence boxes and a computer. Even after the FBI uncovered the affair, Petraeus planned to keep his job, hoping it would stay secret, advisers who served with him in Iraq tell the Washington Post. "But once he knew it was going to go public, he thought that resigning was the right thing to do," says Peter Mansoor, the general's executive officer during the Iraq surge. Broadwell's father claims his daughter is the victim of character assassination. "This is about something else entirely, and the truth will come out," he tells the New York Daily News. "There is a lot more that is going to come out. You wait and see. There’s a lot more here than meets the eye."
