WASHINGTON (AP) A man who worked as a politically appointed State Department official in former President Donald Trump s administration was convicted Thursday of charges that he attacked police officers during the Capitol riot on Jan. 6, 2021.

U.S. District Judge Trevor McFadden heard testimony without a jury before he convicted the former official, Federico Guillermo Klein , and a co-defendant, Steven Cappuccio, of assault charges and other felony offenses stemming from the riot at the U.S. Capitol by a mob of Trump supporters .

Klein and Cappuccio were among nine co-defendants charged with crimes related to one of the most violent and pivotal episodes of the Jan. 6 siege: brutal waves of hand-to-hand combat between rioters and police officers in a tunnel leading to a Capitol entrance on the Lower West Terrace.

Klein and Cappuccio converged on the tunnel as outnumbered police officers struggled for hours to hold back the mob of rioters, prosecutors said in a court filing .

McFadden convicted Klein of 12 counts, including six charging him with assaulting, resisting or impeding police officers. Klein is scheduled to be sentenced on Nov. 3.
