Biden plans to tell his audience, “The next few days, when these bills come to a vote, will mark a turning point in this nation.”

“Will we choose democracy over autocracy, light over shadow, justice over injustice? I know where I stand. I will not yield. I will not flinch,” he’ll say, according to prepared remarks. “I will defend your right to vote and our democracy against all enemies foreign and domestic. And so the question is where will the institution of United States Senate stand?”

A White House official, previewing the speech on the condition of anonymity, said Biden would voice support for changing the Senate filibuster rules only to ensure the right to vote is defended — a strategy Democrats have been looking to the president to embrace. Filibuster rules require 60 votes to advance most legislation — a threshold Senate Democrats can’t meet on their own with their thin, 50-50 Senate majority. Republicans unanimously oppose the voting rights measures.
