Will the U.S. make daylight saving time permanent? President Trump wants to make daylight saving time permanent. Senator Tom Cotton does not. On Saturday, that disagreement led the president to share what he said was the Arkansas Republican’s cellphone number on social media, urging the state’s residents to take the issue up with Mr. Cotton personally. Mr. Trump, championing the Sunshine Protection Act, which has been stalled in the Senate since July, accused Mr. Cotton of holding up the bill in a lengthy Truth Social post. Then Mr. Trump shared 10 digits. “To the Great People of Arkansas, please let your Senator know it would be a GREAT Bipartisan WIN for the United States Senate,” Mr. Trump said. “Call Tom on his cellphone.” Two officials confirmed that the number Mr. Trump gave out belonged to Mr. Cotton, whose office did not respond to a request for a comment. The officials spoke on the condition of anonymity because they were not authorized to discuss the matter publicly. Calls went to an automated voice mail greeting saying an unnamed recipient was “temporarily unavailable.” The bill, which would cement daylight saving time and stop Americans from having to change their clocks twice a year, has been stuck in the Senate after sailing through the House in July with a 308-to-117 vote.
