Romney accuses Biden of 'doubling down on denial'

CHESTERFIELD, Va. -- Mitt Romney renewed his criticism Friday of the Obama administration's response to the deadly terrorist attack on the U.S. Consulate in Libya, accusing Vice President Biden of not being honest with the American people.

The Republican presidential nominee said Biden "directly contradicted" testimony from State Department officials during the vice presidential debate Thursday night, and slammed the VP for "doubling down on denial."

"When the vice president of the United States directly contradicts the testimony, sworn testimony, of state department officials American citizens have a right to know just what's going on," Romney continued, telling the audience that's exactly what he intends to do.

The answer in question came after Biden told the moderator he was unaware of requests by U.S. officials in Libya for more security.

"We weren't told they wanted more security there," Biden said, before repeating himself to highlight the point. "We did not know they wanted more security."

The attack, which took place on the 11th anniversary of the 2001 Sept. 11 terror attacks, left four people dead, including the U.S. ambassador, Christopher Stevens.

Republicans seized on the comments, pointing to testimony by two State Department officials during a House Oversight Committee hearing Wednesday as proof the administration knew. The two officials said a request for more security was turned down by the State Department, but conceded the extra manpower would not have resulted in a different outcome.

White House spokesman Jay Carney clarified Biden's comments Friday, saying the vice president was "speaking directly for himself and for the president," and that the appropriate people in the State Department handled the request, not the White House.

Following the event Friday, an Obama campaign spokesperson accused the former Massachusetts governor of politicizing the event to garner votes. 

"Mitt Romney has repeatedly rushed to launch political attacks without knowing all the facts," Obama campaign spokesperson Lis Smith said in a statement. "The American people deserve more from someone who wants to be Commander-in-Chief."

In recent days, Romney has used the incident in Libya to draw sharp contrasts between his ideas on foreign policy and those of the president. He argues for a more robust foreign policy, and says the president is too passive - reacting to events rather than shaping them.
