The man parading a Confederate flag through the halls of Congress during the Capitol riot last week has been arrested, authorities said Thursday.

Kevin Seefried was charged with violent entry and disorderly conduct on Capitol grounds, according to the criminal complaint. His son Hunter Seefried, who was also at the riot, was slapped with the same charges.

The Seefrieds, who live in Delaware, entered the Senate Building at around 2:13 p.m. on Jan. 6 through a broken window, the complaint says. Kevin Seefried was photographed holding the Confederate banner shortly after they pair entered the building.

The father-son duo then joined other rioters in a 15-minute verbal confrontation with several U.S. Capitol police officers, which was captured on camera by Capitol police.

Hunter Seefried’s co-worker reported the men to the FBI, “relaying that Hunter Seefried had bragged about being in the Capitol with his father,” the complaint says. The co-worker also confirmed photos of Hunter Seefried posted by the Metropolitan Police Department.

The FBI interviewed father and son separately Jan. 12, where both admitted to taking part in the riot. Seefried told authorities he brought the Confederate flag from his Delaware home, where it’s usually displayed outside.

Both men are expected appear in court by Thursday afternoon.
