Democratic Senator Chuck Schumer used what many have been calling a threat to the GOP following the confirmation of Amy Coney Barrett to the Supreme Court by the Senate.
"My colleagues may regret this for a lot longer than they think," said Schumer on the Senate floor during a speech.
"I want to be very clear with my Republican colleagues. You may win this vote ... but you will never, never get your credibility back."
"And the next time the American people give Democrats a majority in this chamber, you will have forfeited the right to tell us how to run that majority. You may win this vote, but in the process, you will speed the precipitous decline of faith in our institution, our politics, the Senate and the Supreme Court."
"My colleagues may regret this for a lot longer than they think. Here at this late hour, at the end of this sordid chapter in the history of the Senate, the history of the Supreme Court, my deepest and greatest sadness is for the American people," the Democrat senator from New York said.
"It will go down as one of the darkest days in the 231-year history of the United States Senate."
Schumer later tweeted a similar sentiment, writing the following in a tweet:
"Today will go down as one of the darkest days in the Senate's 231-year history. The Senate GOP is thwarting the will of the people and confirming a lifetime appointment to the Supreme Court in the middle of a presidential election. Democrats will never stop fighting for Americans."
Some people responding to the tweet went quite a bit further in their sentiments, advocating for militant behavior no matter who wins:
