A U.S. Secret Service officer was injured in an assault while on patrol outside the White House on Saturday shortly after the major immigration rally in Lafayette Park, according to newly filed federal court records. 

Steven Carmona is accused of illegally parking his BMW along Pennsylvania Avenue, moving a bicycle rack-style security barrier erected for the rally and screaming at the officers "Where is the president?" according to a Secret Service affidavit obtained by the News4 I-Team.
