Donald Trump was “most culpable” for the January 6 riot and would have been convicted in court had the case gone to trial, according to explosive testimony from former special counsel Jack Smith, released Wednesday afternoon by the House Judiciary Committee.

Smith led both Justice Department prosecutions of Trump: the first over the January 6, 2021 attack on the U.S. Capitol by his supporters after he lost the 2020 election, and the second over his alleged concealment of classified materials at his Mar-a-Lago club in Florida.

He testified before the Judiciary panel in a closed-door session earlier in December as the committee investigates whether Trump was politically targeted by the Justice Department under Attorney General Merrick Garland and President Joe Biden.
