WATCH: Correspondents' dinner shooting suspect seen running through security in surveillance footage

WASHINGTON (AP) — Federal prosecutors released a video Thursday showing the moment authorities say a man armed with guns and knives tried to storm the White House Correspondents' Association dinner and attempt to kill President Donald Trump. Watch a clip of the footage in the video player above. Jeanine Pirro, the U.S. attorney for Washington, posted the video on social media amid questions over whose bullet struck a Secret Service officer as Cole Tomas Allen ran through security with a long gun toward the hotel ballroom packed with journalists, administration officials and others.

Pirro, however, said Thursday that there is no evidence that the officer was hit by friendly fire. The video appears to show Allen run through a magnetometer and point his weapon at the agent, who fired back five times, according to authorities. It's not clear from the video at what moment Allen's weapon fires. Watch the full video footage below. Allen was injured but was not shot during the Saturday night attack
