"This is what we have been praying for since the beginning of the Trump presidency: the end of the Trump presidency," Colbert said in his opening monologue.
Colbert told his audience of "the live testimony today is as noticeable as it has become."
"This is the largest rating for C-SPAN 3 since & # 39; Drunk History starring Brett Kavanaugh, & # 39;" Colbert joked.
Colbert explained that the star witness was US top diplomat in Ukraine Bill Taylor, whose host was compared to a "grandmother who tells you (whippersnappers) to knock a horse."
Colbert was not the only late-night host with anything to say about the impeachment hearing. ABC's Jimmy Kimmel also enjoys talking about the hearings, but he's celebrating today for a different reason.
"Thank you for joining us on one of the most historic and important dates in U.S. history, my birthday," Kimmel, who turned 52 on Wednesday, told his audience.
Kimmel said his birthday wasn't a big deal for him, but "he got exactly what I wanted this year" thanks to the hearings.
"This is a stressful day for the President," Kimmel said. "Popeyes near the White House, they had to renounce their two-chicken-sandwiches-per-person limit today for him."
As for Seth Meyers, the host of NBC's "Late Night" spent almost 13 minutes talking about the hearings on his segment "A Closer Look."
"Today is a historic day. It is the fourth time in American history that Congress has launched public impeachment proceedings against a sitting chair, and that's not a club you want to be, "Meyers said. "There were two presidents who were really impeached and the third, Richard Nixon, who was so desperate to prevent it, he quit." "If it turned out to be Trump, the Secret Service would have to tie him to the helicopter by his leg and lift him up in the air," he said.
