“The ‘Capitol Siege’ refers to the events of January 6, 2021, when thousands of individuals entered the U.S. Capitol and U.S. Capitol grounds without authority, halting the Joint Session and the entire official proceeding of Congress for hours,” Matthew Graves, the U.S. attorney for the District of Columbia, wrote in a footnote to a February 10 filing. Graves commended Capitol and D.C. Metro police for “clear[ing] the Capitol of rioters” that afternoon.
