President Trump pushed for the Sunshine Protection Act after a midterm loss for the G.O.P. He complained about early darkness on social media, saying, "I will keep fighting for this!" While scientists worry about health risks, the president wants to lock clocks on daylight saving time to enjoy more golf.

Following an election-year rout for Republicans, Trump castigated lawmakers for not passing the Sunshine Protection Act. Some scientists have warned against the change.

The day after a midterm drubbing for the G.O.P., President Trump took to social media to complain -- about turning back the clocks.

"It's so dark outside, so early," he posted on Truth Social. He went on to lament the lack of action taken by the Senate on the Sunshine Protection Act, which would lock most of the nation's clocks on daylight saving time year-round.

"I will keep fighting for this!" he wrote.

Scientists aren't particularly keen on permanent daylight saving time, fearing more injuries in the early-morning darkness and the health consequences of disturbed body clocks. But the president is an ardent supporter. One possible reason: golf.

"Trump is not hiding the fact that golf is definitely on his mind," said Jay Pea, the founder of Save Standard Time, which advocates adopting year-round standard time.

The Sunshine Protection Act was passed by the House in July. The Senate has yet to put the bill to a vote this year, though lawmakers are scheduled to reconvene next week.
