The Short Version
Every material element of this claim is confirmed by authoritative sources, led by the U.S. Department of Justice's own press release. Cole Tomas Allen was indeed charged with attempting to assassinate President Trump in connection with the April 25, 2026 shooting at the White House Correspondents' Association Dinner in Washington, DC. The only counterargument — that the claim misidentifies the venue as "the White House" — misreads the event's proper name and finds no support in any source.
