A leading House Republican is challenging the White House's initial account that the attack on the U.S. Consulate in Libya was a spontaneous assault tied to protests over an anti-Islam video.
President Barack Obama has said extremists used the video as an excuse to launch the attack, which killed U.S. Ambassador Chris Stevens and three other Americans.
Rep. Mike Rogers of Michigan, who chairs the House Intelligence Committee, told CNN's "State of the Union" Sunday he'd seen "no information" that anti-film protests were ongoing prior to the assault and that the administration was "ill-advised" to link the two.
Robert Gibbs, a senior adviser to the Obama campaign, told Fox News Sunday that the investigation continues and "no one wants to get to the bottom of this more than the president."
