Donald Craighead, who had weapons in swastika-tagged truck near DNC,

A judge Tuesday ordered a California man to be held without bond, a day after he was arrested near the Democratic National Committee Headquarters in Washington, D.C., where police say they found weapons in a pickup truck displaying white supremacist symbols.

Court documents showed the man, 44-year-old Donald Craighead of Oceanside, California, making a series of racist, bigoted and otherwise bizarre comments to law enforcement officers before and after his arrest.

Craighead “exhibited signs of possible mental illness” throughout an interview with two special agents Tuesday morning, the officers said in a court filing summarizing the incident.

“Specifically, the defendant advised that prior to being stopped by the police, he was ‘patrolling’ for individuals that were trying to change his magnetic frequency, and the gay families behind the September 11th attack that have stalked him for years,” the agents wrote.

Craighead was charged in Washington Superior Court with carrying a dangerous weapon outside his home or place of business. An attorney for Craighead pleaded not guilty on his behalf and told the judge that “most of his history, with the exception of one incident,” is nonviolent.

Magistrate Judge Lloyd Nolan Jr. ordered him detained without bond until his next court date on Sept. 28.

Craighead was stopped around midnight Monday after officers noticed the truck, which had a Nazi swastika painted on the driver’s side mirror and an “American flag printout” where the driver’s license should be, idling in front of the DNC headquarters building, according to an affidavit.

Once stopped, an officer noticed “a large single edged bayonet style knife with a blade approximately 15 inches long” on the passenger’s seat of the Dodge Dakota pickup, the affidavit said. Another court document said that upon further review, that item was actually a large hunting knife with a blade roughly 7.5 inches in length.

Craighead was placed in handcuffs. When asked whether there were more weapons in the truck, he told officers about a 21.5-inch-long machete in a black sheath on the front dashboard, according to the affidavit.

Craighead then asked one of the officers why he was being pulled over “when there are Brown people hurting white people,” according to the affidavit.

Craighead used homophobic slurs in conversation with the officers. He was wearing a T-shirt associated with the far-right “boogaloo movement,”
