(NBC) The House and Senate Intelligence Committees investigating the September attack on the U.S. consulate in Benghazi, Libya will hear from former CIA Director David Petraeus today.
"He interviewed many of the people as I understand it that were involved and so the opportunity to get his views I think is very important," Senate Intelligence Committee Dianne Feinstein said before her hearing.
The closed-door hearing is not expected to get into the affair that prompted Petraeus to resign.
The CIA is now investigating whether he did anything wrong professionally.
The FBI concluded it was a personal matter.
On Thursday lawmakers saw a real-time video of the Benghazi attack, and got into a heated shouting match over whether United Nations Ambassador Susan Rice intentionally misled the public when she said it was spontaneous.
"This administration, including the President himself, has intentionally misinformed, read that LIED, to the American people in the aftermath of this tragedy," said California Republican Rep. Dana Rohrabacher.
"If you want to know who is responsible in this town, buy yourself a mirror," Rep. Gary Ackerman of New York, referring to the fact that Congress denied requests for funding for increased security at the consulate.
Petraeus could shed some light on the issue.
Today's hearing is closed. The Senate committee expects to hold an open, public hearing at a later date.
