A Boulder man and his father were arrested this month after they tried to push past the police who were guarding the U.S. Capitol building during the riot by supporters of President Donald Trump on Jan. 6, 2021, according to the FBI. Boulder resident Jonathan “Duke” Valentour, 26, was arrested on Monday, the fourth anniversary of the attack on the Capitol. His father, Joseph Valentour, 66, of Centerville, Ohio, was arrested Friday in that state. Both are charged with assaulting, resisting or impeding police officers and obstructing police, both felonies. They are also charged with five misdemeanors, including disorderly conduct and carrying out physical violence at the Capitol. The two men were initially identified from surveillance footage more than two years after the attack, according to an FBI affidavit. Investigators preliminarily linked the men to the surveillance video through publicly available photos in 2023 and conducted interviews over the following year, the affidavit states. Joseph Valentour pushed against police officers and appeared to try to disarm an officer, forcing the officer to fall down a set of stairs, the FBI alleged in an affidavit. Joseph Valentour also attempted to tackle a police officer who moved to try to help the officer who’d fallen down the stairs, the FBI alleged. His son, Jonathan Valentour, was seen on video pushing against police lines with other rioters multiple times, at least once using a police shield as cover during the effort, according to the affidavit. Jonathan Valentour retreated from the riot when he was pepper-sprayed, according to the document.

Trump, who will be inaugurated Jan. 20 to a second term, has called the bloody attack by his supporters “a day of love” and has promised to pardon rioters who have been convicted of crimes related to that day once he is back in office. It’s unclear, so far, whether he will try to pardon all of them or just those who were not violent. The Associated Press contributed to this report.
