A D.C. Superior Court judge on Tuesday ordered a Florida man charged Monday with carrying three guns and more than 100 rounds of ammunition to the U.S. Capitol to undergo a psychological exam after the man refused to cooperate with the judge’s order.

Magistrate Judge Michael McCarthy had ordered Ty C. Mitchum, 59, of Clearwater, Fla., to undergo the competency screening during Mitchum’s initial court appearance Monday following his arrest Sunday for carrying the weapons onto the Capitol grounds.

In court, Mitchum repeatedly refused to cooperate and said he did not want the D.C. attorney who was appointed to represent him. Instead, Mitchum said he wanted his attorney from Tampa. “I have the right to remain silent and I will wait for my attorney.”

New information about Mitchum’s visit to the Capitol was revealed during the hearing Tuesday. McCarthy, reading from a court document, said Mitchum told police at the time of his arrest that he was in Washington regarding his role in “helping take down Osama bin Laden’s terror.”

When the judge asked Mitchum whether he had spent time in the military, Mitchum bowed his head and refused to respond.

“We are trying to help you. We want you to talk to the doctor so we can make sure you are competent,” McCarthy said. McCarthy said Mitchum would remain in D.C. jail until he cooperates. Mitchum is scheduled to return to court again Wednesday.
