Brad Pitt made a joke about the Senate impeachment trial during his Oscars acceptance speech Sunday night. While on stage for his best supporting actor win, Pitt said he had more time to speak than former White House national security adviser John Bolton, who wasn't allowed to testify during President Donald Trump's impeachment trial.

Pitt, who won his first-ever acting Oscar for his role as stunt double Cliff Booth in "Once Upon a Time in Hollywood," thanked the movie's director Quentin Tarantino and his co-star Leonardo DiCaprio. He also took a shot at the Republican-controlled Senate for voting against witnesses to appear in the trial.

"They told me I only had 45 seconds up here, which is 45 seconds more than the Senate gave John Bolton this week," Pitt said.

Backstage, Pitt explained his reference to the impeachment hearings, which ended in an acquittal for Trump.

“I was really disappointed with this week,” he said. “When gamesmanship trumps doing the right thing, it’s a sad day and I don’t think we should let it slide. I’m very serious about that.”
