President-elect Donald Trump issued a brief statement saying that Republicans would work to end Daylight Saving Time.

DST was proposed by Ben Franklin in 1784 as a way to increase productivity by allowing people more time to sleep when it is dark. The policy was adopted in 1918 in the U.S., but many states refuse to participate, including Arizona, Hawaii, and the territory of Puerto Rico.

Trump offered an explanation why he believes ending DST is in Americans’ interests.

Daylight Saving Time is inconvenient, and very costly to our Nation,” he wrote on social media. (Read more from “Trump Says He Will Eliminate Daylight Saving Time” HERE)
