The man charged with carrying a loaded shotgun and possessing an explosive device near the Capitol filed an additional motion in court Tuesday to recuse the judge and prosecutors from his trial.

Michael Gorbey, 38, is representing himself in the case. Earlier this month, he filed a range of other motions, including one to dismiss his case and another to suppress evidence seized by police.

Judge Gregory Jackson scheduled a hearing for Monday, the day Gorbey’s trial originally was slated to begin, to address the motions. The trial could now be moved back a day or two, as jury selection also is scheduled for Monday.

The U.S. Attorney’s Office for the District of Columbia has charged Gorbey with 15 counts, including unlawful possession of a firearm, unlawful possession of ammunition and attempted manufacturing of a weapon of mass destruction.

Gorbey has pleaded not guilty to all the charges.

Capitol Police arrested Gorbey on Jan. 18 after he was spotted carrying the shotgun and a range of other weapons on Capitol Hill. Police also seized a pickup truck that they believe Gorbey used to drive to Capitol Hill.

During a follow-up investigation three weeks later, police discovered an explosive device in the truck.

Gorbey previously filed a motion to change court venues, citing the extensive publicity his case has already received. Jackson denied that motion, saying the news coverage has not been extensive enough to warrant such a change.
