Biden pointed to the recent fight over the debt ceiling, where Republicans threatened for weeks that they wouldn’t help advance a debt hike before backtracking and providing 11 GOP votes for a short-term increase.

“If that gets pulled again, I think you are going to see an awful lot of Democrats being ready to say, not me. I’m not doing that again. We’re going to end the filibuster. But it still is difficult to end the filibuster beyond that,” he said.

He added that he was “open to fundamentally altering” the legislative filibuster, including on voting rights and “maybe more.”

Biden’s remarks won immediate praise from progressives and activists.

“Glad to hear [Biden] call to bring back the talking filibuster. If Republicans want to block enormously popular policies like protections for our freedom to vote, they should have to hold the floor and do it in public,” said Sen. Jeff Merkley (D-Ore.), a longtime advocate for Senate rules reforms.
