President-elect Donald Trump said Friday he and Republicans will seek to permanently eliminate daylight saving time when he takes office.

In a post on TruthSocial, Trump wrote: “The Republican Party will do its best to abolish Daylight Saving Time, which has a small but powerful constituency, but it shouldn’t!” Daylight saving time is inconvenient and very costly to our nation.”

Two of Trump’s top advisers, technology mogul Elon Musk and entrepreneur Vivek Ramaswamy, whom the president-elect has tapped to lead a new Department of Government Efficiency, have also floated the idea of ​​eliminating time changes.

“Looks like people want to get rid of the annoying time changes!” Musk wrote on X last month.

Replying to him, Ramaswamy wrote, “It is inefficient and easy to change.”

Donald Trump Jr., the president-elect’s son, also responded to Musk’s post but appeared to take an opposite position to his father’s.

“Always keep it daylight saving time,” Trump Jr. wrote, adding several emojis of the number “100” to signal his approval of Musk.

The younger Trump’s position is in line with a bill passed by the Senate in 2022 that would have made daylight saving time permanent starting the following year.

Sen. Marco Rubio, R-Florida, backed the proposal again in 2023 after it stalled in the House. Trump has announced that he will nominate Rubio as his next secretary of state. It’s unclear who would replace him if confirmed, but Lara Trump, the president-elect’s daughter-in-law, has been floated as a potential candidate.

The 2022 bill was co-sponsored by a bipartisan group of senators, including Sens. James Lankford, R-Okla., Ron Wyden, D-Ore., Cindy Hyde-Smith, R-Miss., Rick Scott, R-Fla. , Tommy Tuberville, R-Ala., and Ed Markey, D-Mass.

The Trump campaign did not immediately respond to questions from NBC News asking whether Trump wants to abolish daylight saving time or make it permanent.

Daylight saving time was introduced in the United States in 1918 to save energy during World War I. However, some parts of the country have opted out. Hawaii and some parts of Arizona do not participate in Daylight Saving Time.
