Newly released surveillance footage offers a chilling look at the moments just before gunfire erupted at the White House Correspondents' Association Dinner. Video released by the U.S. Attorney's Office appears to show suspect Cole Allen quickly moving through a security checkpoint just before the shooting at the Washington Hilton during the high-profile event. Allen is accused of attempting to assassinate President Donald Trump during the annual dinner, which was attended by top political figures, journalists and members of the Trump administration.
