A Virginia man arrested after falsely reporting his car trunk contained a bomb at a U.S. Secret Service checkpoint outside the White House was ordered to undergo a mental competency examination and remain jailed until a hearing Thursday.

Sean Patrick Keoughan, 29, of Roanoke, faces a statutory maximum penalty of 10 years in prison if convicted of making a false bomb threat Saturday night, U.S. Magistrate Robin M. Meriweather of the District said at Keoughan’s first court appearance Monday.

Meriweather ordered a 24-hour competency examination by D.C. court officials as requested by assistant federal defender Dani Jahn, which prosecutors did not oppose. The magistrate put on hold for now a request by assistant U.S. attorney Erik Kenerson for a 30-day psychiatric evaluation for Keoughan under U.S. Bureau of Prisons detention.

Jahn said Keoughan, bearded and dressed in a checked shirt, hooded blue rain jacket and jeans with a torn back pocket, appeared to understand the proceedings against him and to be able to assist in his defense.

Kenerson said a competency exam was justified based on statements Keoughan allegedly made to a uniformed Secret Service officer. An arrest affidavit filed with the court charges:

At about 11:05 p.m. Saturday at a checkpoint at 15th and E streets NW, Keoughan pulled up in a black Chevrolet Impala and said he was carrying a bomb and, later, an asteroid in a canvas bag in the trunk; that he had been directed to test the checkpoint by President Trump; and that he was in telepathic communication with Trump, the Secret Service and Delta Force through a system called “Think Talk.”
