After Oath Keepers charges, could feds accuse Capitol attackers of conspiring to overthrow U.S. government? Kevin McCoy and Kevin Johnson, USA TODAY US Capitol Police officers faced violent attacks from pro-Trump supporters during riots Replay Video Federal investigators have signaled some of the defendants in the attack on the U.S. Capitol could be charged with seditious conspiracy, a law enacted to target those who attacked the federal government during the Reconstruction era. An indictment filed on Jan. 27 charges three of the riot suspects with conspiring to impede Congress' certification of the Electoral College vote for the 2020 presidential election. The filing alleges those three are members of the Oath Keepers, "a loosely organized collection of militia who believe that the federal government has been co-opted by a shadowy conspiracy that is trying to strip Americans of their rights."
