President Trump published Sen. Tom Cotton's personal cellphone number on Truth Social this weekend, urging his followers nationwide to flood the Arkansas Republican's phone with calls over a stalled bill to end the twice-a-year clock change.

The posts began late Thursday into Saturday, October 3, with Trump pushing what he's branded the "No More Changing of Clocks Act" — legislation that would lock the country into permanent daylight saving time. "Republicans in the Senate have to get moving" on the bill, Trump wrote, adding that it was "being held up by Senator Tom Cotton, of Arkansas, for reasons unknown." He then told supporters to "Call Tom on his cellphone. Tell Tom to, GET IT DONE!"

The bill in question, the Sunshine Protection Act, cleared the House in July with bipartisan support before stalling in the Senate. Trump has framed the fight in distinctly tabloid-ready terms, arguing in a separate post that permanent daylight saving time would spare the country the cost of resetting clocks on "tall structures like church steeples" and would hand extra evening sunlight to "golfers, tennis players, hunters, and farmers."

Cotton fires back

Cotton, one of the Senate's most vocal holdouts, didn't back down. Congress has flipped on permanent daylight saving time before, he noted, and reversed itself each time once the public experienced the darker flip side of the trade-off.

"Arkansans don't want their kids going to school in the pitch dark, and I'll always put Arkansas first," Cotton said, pointing out that "Congress has enacted permanent Daylight Savings Time multiple times before and repealed it each time once Americans experienced absurdly late sunrises in the winter."

Trump pushed back again, telling Cotton to "TAKE THE WIN" for the party and ditch his objections for the sake of ending the twice-yearly ritual altogether, signing off with a trademark "LOCK THE CLOCK!"

The move instantly drew comparisons to a 2015 episode in which Trump broadcast Sen. Lindsey Graham's cellphone number during the GOP presidential primary — a stunt that ended with Graham destroying his phone on live television. Multiple outlets, including KSL News, reported that calls to the number went to a voicemail that did not identify its owner when reporters tried it themselves.

Cotton's office has not said whether the senator's actual personal line was flooded with calls or texts in the hours after the post went up, nor whether he plans to change the number. The senator, for his part, has given no indication he intends to drop his opposition.

The broader fight over permanent daylight saving time remains unresolved on Capitol Hill, with the House-passed bill still awaiting Senate floor action. Whether Trump's public pressure campaign moves votes — or just burns up Cotton's inbox — is likely to become clear in the coming days as the Senate returns to session.
