Brad Pitt's Oscars 2020 speech mocks senators for not calling John Bolton to testify at impeachment trial

The four-time Academy Award nominee won the best-supporting actor accolade for his role as a stuntman in “Once Upon a Time in Hollywood.” He immediately took the stage and got political by taking a jab at senators who voted against Democrats request to call witnesses in the impeachment trial, specifically former National Security Adviser John Bolton, who claimed he was willing to testify.

“They told me I only have 45 seconds up here, which is 45 seconds more than the Senate gave John Bolton this week,” Pitt said. “I’m thinking maybe Quentin [Tarantino] does a movie about it. In the end, the adults do the right thing.”

No witnesses were called in Trump's impeachment trial, for which he was ultimately acquitted by the Senate in a vote across party lines, with the exception of a lone Republican vote to convict coming from Sen. Mitt Romney.

Pitt had been expected to win the category after scooping up a series of honors this year, including at the Golden Globes and Screen Actors Guild Awards. Pitt’s politically driven tone was significantly different than previous wins, where he kept it light with jokes and breezy speeches.

Pitt was more somber on Sunday, calling his win “incredible” as his peers cheered.
