Petraeus to testify before Congress on Thursday, Friday

The former CIA director is set to attend hearings on Libya attack.

Former CIA Director David Petraeus, who stepped down last week because of an extramarital affair, will testify before Congress this week on the terrorist attack in Libya that killed four Americans.

Petraeus will testify on Thursday before the Senate Intelligence Committee, according to NBC News, and on Friday at 7:30 a.m. before the House Intelligence Committee in a closed-door hearing open only to lawmakers, the committee said in a statement on Wednesday night.

Meanwhile, the FBI agent who helped kick off the investigation that uncovered Petraeus’s affair and led to his resignation was identified by law enforcement colleagues on Wednesday as Frederick W. Humphries II, The New York Times reported.

Humphries reportedly took the initial complaint from Jill Kelley, a personal friend, about threatening, anonymous e-mails -- later discovered to be sent by Petraeus biographer Paula Broadwell -- that accused her of flirting with Petraeus. A spokesman for Kelley said she reported the e-mails to Humphries because she feared the sender was “stalking” Petreaus and Gen. John Allen, the commander of NATO forces in Afghanistan, The Times reported.

The complaint kicked off the investigation that uncovered the extramarital affair between Petraeus and Broadwell. The investigation also implicated Allen after the FBI discovered “potentially inappropriate” e-mails between him and Kelley.
