WASHINGTON (AP) — Republican senators are demanding that the Obama administration make public the surveillance video taken during last month's deadly attack on the U.S. Consulate in Libya, which killed the U.S. ambassador and three other Americans.

Sens. John McCain, Lindsey Graham and Kelly Ayotte wrote to President Barack Obama's defense secretary, CIA director and attorney general demanding that the video be declassified.

In the run-up to the presidential election, Republicans have accused the Obama administration of distorting the account of the attack on Sept. 11 that killed Ambassador Chris Stevens and three other Americans. Officials first blamed it on a mob set into motion by an anti-Islamic film. Obama administration officials have pointed to U.S. intelligence reports that showed conflicting information. Administration officials did not respond to requests for comment.
