Top intel official to hold House-wide Libya briefing this week

Top U.S. intelligence official James Clapper plans to hold a House-wide, classified briefing Wednesday on the Libya terror attack, Fox News has learned.

The bipartisan briefing is set for Wednesday morning and is expected to include a host of top officials at the center of the controversy. 

Lawmakers continue to raise concerns about the administration's initial claim after the attack that it was a "spontaneous" act that sprung out of protests over an anti-Islam film. The administration has since acknowledged that, while demonstrations were raging in Cairo, there was no protest in Benghazi at the time of the attack.

U.S. Ambassador to the U.N. Susan Rice took heat for repeatedly citing the film in interviews five days after the strike. But officials have blamed flawed intelligence for the assessment.

Further, lawmakers want to know more about what warning signs the administration might have had in the weeks and months leading up to the attack.

The briefing Wednesday is set to include State Department Undersecretary of Management Patrick Kennedy and Director of the National Counterterrorism Center Matthew Olsen.

The closed briefing will include a "multimedia presentation."

The Sept. 11 Benghazi attack left four Americans dead, including Ambassador Chris Stevens.
