Rosie O'Donnell — who's been engaged in a longtime public feud with Trump — posted a video of herself on Twitter praising Pelosi's words. 

"Thank you, Nancy Pelosi!" O'Donnell, 57, exclaimed. "Listen, I never thought this day would come," she said to her more than 1 million followers.

Comedian Kathy Griffin — who in 2017 ignited controversy when she posed for a photo shoot with a fake severed head resembling the president — simply lauded Pelosi as "flawless."

"Will & Grace" star Debra Messing, another performer who has repeatedly sparred with Trump, also heaped praise on Pelosi.

Ahead of Pelosi's remarks, "When Harry Met Sally" director Rob Reiner expressed support for an impeachment inquiry.

The move to begin impeachment proceedings against Trump comes amid reports of an intelligence community whistleblower complaint that raised concerns about the president's interactions with the leader of Ukraine.
