Justice Department releases selfie suspect in latest Trump assassination attempt took moments before trying to storm ballroom

Cole Tomas Allen.

The U.S. Department of Justice on Wednesday release a detention memo, which makes the case that Cole Tomas Allen should remain in custody while awaiting trial on charges that he attempted to assassinate the President of the United States. Among the materials released in the memo was a selfie officials say he took about 30 minutes before his alleged attack.

According to the memo, the crimes Allen stands accused of "are among the most serious in the United States Code, and the evidence of his guilt is overwhelming." Among the supporting evidence prosecutors included in the memo were photos of Allens arsenal of weapons -- multiple knives, a handgun, and the rifle authorities say Allen carried as he bolted toward the ballroom at the Washington Hilton, as well as ammunition, pliers and a pair of wire cutters. 

Prosecutors also revealed a photo taken at 8:03 p.m. on Saturday night, less than 30 minutes before the attack, that was found on Allen's cellphone. The image is a selfie of Allen looking in the mirror and shows him wearing a black dress shirt, black pants, a red necktie as well a shoulder holster, one of the knives that investigators found on him and pliers and wire cutters.

Prosecutors say at 8:27 p.m. he used his phone to check in on a livestream of the White House Correspondents' Dinner to confirm that President Trump had arrived. Moments later, he charged the ballroom before being apprehended by Secret Service agents. Allen faces life in prison of convicted of the attempted assassination charge and related firearms charges.
