Facing a potential indictment, Donald Trump took a defiant stance at a rally Saturday in Waco, disparaging the prosecutors investigating him and predicting his vindication as he rallied supporters in a city made famous by deadly resistance against law enforcement.

With a hand over his heart, Donald Trump stood at attention when his rally opened with a song called “Justice for All” performed by a choir of people imprisoned for their roles in the Jan. 6 insurrection at the U.S. Capitol. Some footage from the insurrection was shown on big screens displayed at the rally site as the choir sang the national anthem and a recording played of Trump reciting the Pledge of Allegiance.
