The commentary comes as Trump's impeachment trial looks to be wrapped up next week after a motion to allow additional witnesses in the president's impeachment trial failed in the Senate by a 49-51 vote Friday evening.

"OK, I’m going to try not to cry during the show because we lost Democracy this week," Maher said. "I feel like I’m standing over a casket and thinking, 'Hmm I should have been nicer when it was alive.'"

"It’s a done deal. This is going to happen," Maher added later in the show. "Trump will be acquitted on Wednesday. Republicans have nothing left to do but dot the i’s, cross the t’s and f--- the u’s.”

The staunch Trump critic also alleged that the president and the GOP-controlled Senate are "corrupt."

“We always knew Trump was corrupt, but now we found out the Senate is too," Maher said.
