A man carrying a knife was arrested outside the White House today because he told a Secret Service agent that he was there to assassinate President Trump.

The man with the knife, Roger Hedgpeth, 25, was arrested for making threats, and his car was impounded.

“I am here to assassinate President Donald Trump,” he told a Secret Service officer, the police report said, according to the Washington Post. “I have a knife to do it with.”

Authorities found a 3.5-inch knife in a sheath on his hip.

Yahoo News reports that Hedgpeth was taken into custody before he was brought to a hospital for a mental health evaluation.

According to the Post, Hedgpeth is from Brandon, Florida. Police said he is a “critically missing/endangered person as well as a mental health consumer.”

A telephone number listed for Hedgpeth in public records rang unanswered on Sunday.

It wasn’t immediately clear where he lives or whether he had a lawyer who could comment on his behalf.

There have been numerous alarming attempts to breach the security around the White House, but this is a different and more serious incident because of the weapon.
