Treasury Secretary Scott Bessent spent his Sunday making the case for something that could fundamentally reshape how Congress works: scrapping the legislative filibuster. His condition? If Democrats force another government shutdown when current funding runs out in late January, Republicans should "immediately end" the 60-vote rule that's been a Senate fixture for generations.

A "Procedural Fossil" That Democrats Weaponized

Writing in a Washington Post opinion piece, Bessent didn't mince words. He called the filibuster a "procedural fossil" that Democrats have used to hold the country "hostage," pointing to the 43-day shutdown that ended November 12 as exhibit A. That shutdown, the longest on record, wasn't just an inconvenience. Bessent cataloged the damage: billions in lost economic output, canceled flights, delayed paychecks for federal workers, and general chaos. In his view, the filibuster now functions as a minority veto that gives the opposition party outsized power to block the majority's agenda.

He doubled down on X, writing: "With the American people just now emerging from the longest and most devastating government shutdown in U.S. history, we cannot ignore the weapon Senate Democrats used to take the country hostage."

His bottom line in the op-ed was clear: "In January, when spending considerations again come due, if Democrats once again choose to shut down the government, then Republicans should immediately end the filibuster."

Trump Wants the Nuclear Option, But GOP Leaders Aren't Biting

Bessent's position mirrors President Donald Trump's, who pushed GOP senators during the shutdown to "go nuclear" on the filibuster. Trump has argued that Democrats would eliminate the rule without hesitation if they regained control, a claim Bessent echoed, calling Republican faith in Democratic restraint "wishful thinking."

But there's a problem: Republican leadership isn't on board. Senate Majority Leader John Thune (R-S.D.) and House Speaker Mike Johnson (R-La.) have both defended the filibuster as an institutional safeguard that protects minority rights and prevents wild policy swings. More importantly, they say the votes simply aren't there to eliminate it.

Do They Actually Have the Votes?

NBC's Kristen Welker pressed Bessent on exactly this point during "Meet the Press" on Sunday. If Thune says Republicans don't have the votes, does Bessent actually know otherwise? Bessent dodged, saying they'll find out by January 30. He framed his op-ed as a shot across the bow, a warning to Democrats and the Senate about what could happen if another shutdown materializes. Whether that's a real threat or political posturing depends entirely on whether he can actually count to 51 votes when it matters.
