Senate Democrats blocked a move by Senate Republicans to modify a Trump-backed voter ID bill with a provision that would halt men in womens sports.The amendment to the Safeguarding American Voter Eligibility (SAVE) America Act from Sen. Tommy Tuberville, R-Ala., was one of several tweaks to the legislation requested by President Donald Trump.Tubervilles amendment could have codified Trumps earlier executive order from last year to ban transgender women from participating in womens sports a culture war flashpoint between Republicans and Democrats that, unless turned into law, will likely be reversed should a Democratic administration take over in 2028.GOP SENATORS GAMBIT EXPOSES FALSE DEM CLAIMS ABOUT SUPPORTING VOTER IDBut, as expected, the add-on failed on a party-line vote in the upper chamber.The amendment was the first of several expected to hit the floor as Republicans continue their takeover strategy to debate the bill. Saturday marked the fifth day that the SAVE America Act dominated the floor."I would do whatever it took to get this passed," Tuberville told Fox News Digital. "This is probably one of the most important bills that's come through here in a long, long time. Its just pitting Americans versus non-Americans."THUNE ACCUSES CRITICS OF 'CREATING FALSE EXPECTATIONS' AMID BACKLASH OVER STALLED SAVE AMERICA ACTOthers on the docket include a ban on transgender surgeries on minors and halting unsolicited mail-in ballots add-ons that Trump requested Republicans tack onto the voter ID and citizen verification bill.And the ongoing floor takeover likely wont result in the SAVE America Act passing, given that Senate Minority Leader Chuck Schumer, D-N.Y., and Senate Democrats are unified in their rejection of the legislation."So I'm like, President Trump, we need to get it done," he continued. "But I don't know whether weve got enough support, even on the Republican side, much less Democrats."REPUBLICANS SIGNAL NO RETREAT ON SAVE ACT AS MARATHON SENATE DEBATE KICKS OFFThe unlimited debate on the legislation is meant to mimic the talking filibuster, a strategy that would lower the threshold to pass the legislation to a simple 50-vote majority at the cost of deadlocking the Senate floor.And Senate Democrats would be able to offer an unlimited number of amendments that could drastically change the bill, which Republicans have acknowledged they dont have the numbers to block.The floor takeover theyre currently undertaking is largely meant to shift blame from Republicans to Schumer and Democrats for the bills expected failure, given that, in order to pass conventionally, the GOP would need 60 votes.But others hope, like Sen. Mike Lee, R-Utah, who is the lead sponsor of the SAVE America Act in the Senate, that the constant debate will grind down Democratic resistance and flip some over to support the bill.
