“If I haven’t said it very plain, maybe Sen. McConnell hasn’t understood, I want to basically say it for you. That I will not vote in this Congress, that’s two years, right? I will not vote” to change the filibuster, Manchin (D-W.Va.) said in an interview on Monday afternoon. “And I hope with that guarantee in place he will work in a much more amicable way.”

Some Democrats say if Republicans block Democrats’ priorities, it’s worth preserving the ability to change the rules later. Asked if there is any scenario that would change his mind, he replied: “None whatsoever that I will vote to get rid of the filibuster.”
