Police say a man from Florida is in custody, accused of threatening to kill President Donald Trump.

According to police, Roger Hedgpeth, 25, was arrested Saturday outside the White House.

Police say Hedgpeth reportedly approached a U.S. Secret Service police officer and announced his intention to kill the president with a knife. The officer confiscated the knife following a pat down search.

The Secret Service says Hedgpeth was a critically missing-endangered person, as well as a mental health patient.

He was moved to a hospital for a mental health evaluation, where he will be held until further notice.
