Senator John Curtis (R-UT) has publicly rejected President Donald Trump's push to eliminate the Senate filibuster, becoming the latest Republican lawmaker to resist the president's demand.

In a Wall Street Journal op-ed published Thursday, Curtis was unequivocal: "Under no circumstance will I support any effort to end or alter the filibuster."

The Utah senator warned that any party choosing to eliminate the procedural rule "wouldn't be guaranteed survival" and that its "agenda would be guaranteed death come the next majority." The filibuster, a long-standing Senate tradition requiring a 60-vote supermajority to advance most legislation, has been a point of contention between Trump and members of his own party.

Curtis defended the filibuster as a safeguard for individual senator independence and minority rights, regardless of which party holds power. He argued that without it, senators could be "easily overruled and pushed aside" by party leadership. The stance reflects a broader institutionalist view held by many senators in both parties who have historically resisted changes to the 60-vote threshold, even when doing so would benefit their own agenda, out of concern that majorities are inherently temporary.

Curtis joins a growing Republican faction resisting Trump's demand to remove the filibuster in order to secure passage of his SAVE America Act, a controversial voting and election bill that would mandate proof-of-citizenship for voter registration, ban private funding of election administration, and impose new rules on mail-in ballots. With Republicans holding 53 Senate seats, passage would require at least seven Democratic votes under current rules—a threshold supporters of the bill have been unable to reach.

Senators Lisa Murkowski (R-AK) and Majority Leader John Thune (R-SD) have similarly declined to support gutting the filibuster to reach the 60-vote threshold that Trump's election overhaul legislation would require.
