Late-night host Stephen Colbert mocked Donald Trump Jr. in his monologue Thursday after Trump Jr.’s lengthy testimony before the House Intelligence Committee earlier this week.

“[It] lasted roughly eight hours, making it the first time a Trump has put in a full day of work,” Colbert said.

Trump Jr. testified before the committee to answer questions about his contacts with Russians during the 2016 election, including a June 2016 meeting at Trump Tower with a Russian lawyer who promised him damaging information on then-Democratic presidential candidate Hillary Clinton Hillary Diane Rodham ClintonButtigieg stands in as Pence for Harris's debate practice Senate GOP sees early Supreme Court vote as political booster shot Poll: 51 percent of voters want to abolish the electoral college MORE.

“Everybody was at the meeting. Paul Manafort, Jared Kushner — it was a real who’s who of who wants an orange jumpsuit,” Colbert said.

The comedian also mocked Trump Jr. for refusing to answer some of the committee’s questions about his conversations with his father regarding the meeting, citing attorney-client privilege. Trump Jr. reportedly said he was invoking the privilege because an attorney was in the room at the time of the discussions.

“Is that how it works?” Colbert said. “If that’s how it works, I’m going to rob a law firm. ‘Alright everybody, hands in the air. Remember, none of you can testify.’”

“My takeaway is he has a very serious case of amnesia and he was pretty nonresponsive on a lot of issues that, frankly, you would have a recollection of, considering it was just a year ago that many of these events took place,” Speier said on CNN.
