President Donald Trump on Tuesday is expected to sign an executive order cracking down on mail-in voting, the White House said.

White House Press Secretary Karoline Leavitt said on X that the president will sign the order at the White House on Tuesday evening. Her statement confirmed earlier reporting by the Daily Caller, which said Trump would sign the order.

According to the Daily Caller, the executive order would require the secretary of the Department of Homeland Security to compile a list of verified U.S. citizens in each state who are eligible to vote. DHS would undertake the effort with the Social Security Administration, the Daily Caller wrote, citing a White House fact sheet.

The U.S. Postal Service would then be required under the order to only send mail-in ballots to voters who appear on the list, according to the Daily Caller. Election authorities in each state typically send out mail ballots to voters, not the Postal Service.

Trump has long sought to restrict mail-in voting following his loss in the 2020 election to former President Joe Biden. He has repeatedly claimed, without providing evidence, that the election was stolen from him due to fraud in mail-in voting.
