During a segment of MSNBC’s “Meet the Press” on Tuesday, neoconservative political analyst William Kristol, better known as Bill Kristol, agreed with 2020 Presidential candidate Elizabeth Warren’s (D-MA) call to begin impeachment proceedings against President Donald Trump.

Earlier in the day, Warren took to the Senate floor to counter Majority Leader Mitch McConnell’s declaration that the “case closed” on the Russia investigation and his rebuke of the Democratic Party’s refusal to accept special counsel Robert Mueller’s "inconclusive" report on whether the POTUS obstructed justice during the 2016 election.

“More than 600 federal prosecutors have now said that what’s laid out in the Mueller report would constitute obstruction of justice, and would trigger a prosecution for any human being in this country other than the president of the United States,” Warren said in a speech. “Robert Mueller put all of the facts together for us, put all of the information together for us, and abided by the Trump administration declaration under the office of legal counsel that a sitting president cannot be indicted for his crimes.”

“We took an oath not to try and protect Donald Trump, we took an oath to protect and serve the Constitution of the United States of America, and the way we do that is we begin impeachment proceedings now against this president,” Warren added.

Hours later, Kristol appeared before a news panel and critiqued the Democrats for being "so terrified about the word impeachment that we can't even have hearings." He further clarified, saying that Democrats "shouldn't do impeachment for the sake of defeating President Trump," adding, "I must say I agree with Elizabeth Warren. I never thought I would say this."

“Robert Mueller’s report… invited Congress to take a look for itself at the obstruction of justice charges. They have an obligation to do it. They don’t have to impeach him. They may take a look and decide there aren’t grounds for impeachment. Maybe they wanna censure him… I think Elizabeth Warren’s right. Begin the hearings,” he said.

Kristol’s words took his panelists by surprise. While host Chuck Todd uttered, “Wow,” one of the show's panelists exclaimed, “I was here.” As the Republican commentator looked surprised himself, saying, “I never thought I’d say this,” Todd remarked, “The Right is going to say: 'Boy, Bill Kristol has really gone over the deep end.’”

Kristol, the founder and editor-at-large of the now-defunct political magazine “The Weekly Standard,” is a longstanding Trump critic, who called for a worthy Republican candidate to challenge the president in the 2020 election, while he was in New Hampshire, in April, local newspaper Fosters.com reported.

He added that while he understood that incumbent presidents have rarely been challenged in the past since “they’re pretty popular in their own party, and people say that challenging him would weaken him and that would be bad for the general,” he reminded conservatives that “if he’s [Trump’s] nominated and re-elected, eight years is a lot longer than four years.”
