The US Department of Justice released security footage Thursday showing Cole Allen, the man accused of attempting to assassinate President Donald Trump, charging through a hotel security checkpoint and shooting a Secret Service officer. The attack occurred Saturday at the annual White House Correspondents’ Dinner in Washington. Allen, 31, faces up to life in prison if convicted.

What does the Justice Department footage of the Trump shooting suspect show?

The nearly six-minute video shows Allen moving through corridors and a fitness center at the Washington Hilton earlier in the day, which US Attorney Jeanine Pirro described as him “casing the area.”

A more dramatic clip then shows a man carrying what appears to be a long-barreled gun sprinting through a security checkpoint past uniformed police and suited agents in under four seconds.

Pirro confirmed the footage shows Allen shooting a Secret Service officer during his attempt to assassinate Trump at the White House Correspondents’ Dinner. She said the video had already been provided to the US District Court.

Was the Secret Service officer shot by friendly fire?

Pirro was direct on the question of friendly fire: “There is no evidence the shooting was the result of friendly fire.” The footage shows a Secret Service agent discharging his weapon three times toward the assailant, though police confirmed Allen himself was not shot during the attack.

A slow-motion clip released by the Justice Department places white circles around the agent’s firearm at each of the three moments a muzzle blast is visible. This sequence helps establish the sequence of gunfire at the checkpoint.

What happened after Allen breached the security checkpoint?

Allen was tackled and detained in a chaotic scuffle with security guards. Shots were fired, but no one was killed. His capture does not appear in the Thursday footage release, and the video does not make clear who sustained the gunshot wound.

What charges does Cole Allen face?

Allen, from California, was charged Monday in federal court with attempting to assassinate the president, a Republican. He faces up to life in prison if convicted. The footage released by the Justice Department is expected to form a central part of the prosecution’s case.
