Assassination Attempt Unveiled at White House Gala

Cole Allen, 31, has been accused of attempting to assassinate U.S. President Donald Trump during a reporters' gala at the White House. On Monday, he entered a not guilty plea to all charges through his attorney.

The charges against Allen include attempted assassination, assault on a federal officer, and firearms offenses. Prosecutors allege Allen fired a shotgun at a Secret Service agent and tried to break through a security checkpoint during the attack.

At his court appearance, Allen wore an orange jumpsuit and was shackled at the waist. The hearing marked his first appearance before U.S. District Judge Trevor McFadden, who will preside over the case. The proceedings followed a prior judge's apology for Allen's treatment in a local D.C. jail, where he was held under suicide precautions and isolated from other inmates.
