Two are charged in the assault of a Capitol Police officer who died after the Jan. 6 riot.

Two men have been charged with assaulting Officer Brian D. Sicknick of the Capitol Police and other officers during the Jan. 6 riot, the Justice Department said on Monday, but prosecutors stopped short of linking the attack to Officer Sicknick’s death the next day.

The F.B.I. arrested George Pierre Tanios, 39, of Morgantown, W.Va., and Julian Elie Khater, 32, of State College, Pa., on Sunday. They were charged with conspiracy to injure an officer, assaulting an officer with a dangerous weapon, civil disorder, obstruction of an official proceeding, and other crimes related to violent conduct on the grounds of the Capitol, the Justice Department said.
