Oath Keepers founder Stewart Rhodes, the far-right extremist group leader convicted of seditious conspiracy in the Jan. 6, 2021, attack, has visited Capitol Hill after President Donald Trump commuted his 18-year prison sentence.

Four years after they raided the Capitol and assaulted police officers, a group of some of the most violent Jan. 6 rioters are now free men.

U.S. Capitol, and Tarrio and Rhodes received the longest sentences of anyone charged in the attack. Both men were prosecuted for helping plan the insurrection, and both were convicted of seditious conspiracy.
