While she’s already called for impeaching President Trump on the campaign trail and on Twitter, on Tuesday, Sen. Elizabeth Warren made the case on the Senate floor.

Reading excerpts from special counsel Robert Mueller’s report on Russian interference in the 2016 election, Warren said "if any other human being in this country had done what's documented in the Mueller report, they would be arrested and put in jail.”

She said the only option left is to begin impeachment proceedings against the president, which is “not a fight [she] wants to take on” but one she is compelled to given what she claims is the evidence against him.

"This is not about politics. This is about the Constitution. We took an oath not to try to protect Donald Trump, we took an oath to protect the Constitution. And the way we do that is we begin impeachment proceedings now against this president."

You and I both took an oath, @SenateMajLdr McConnell. To defend the Constitution of the United States – not to protect @realDonaldTrump. Congress must consider the evidence provided in the Mueller Report and hold the President accountable. https://t.co/H2aoBCl7AD — Elizabeth Warren (@SenWarren) May 7, 2019

Her remarks came after Senate Majority Leader Mitch McConnell urged his colleagues to move on from the Russia investigation, which he determined to be "case closed."
