President Trump suggested Tuesday that Colorado's embrace of mail-in voting played a role in his decision to move Space Command's headquarters from Colorado Springs to Huntsville, Ala.

"The problem I have with Colorado, one of the big problems, they do mail-in voting. They do all mail-in voting. So they have automatically crooked elections," Trump said. "And we can’t have that. When a state is for mail-in voting that means they want dishonest elections, because that’s what that means."

"So that played a big factor also," he added.

Asked later whether he was concerned that some officials with Space Command may not want to relocate to Alabama, Trump again pointed to Colorado's voting policies.

"The problem with Colorado is they have a very corrupt voting system," Trump said.

Trump has for years spread unproven claims about widespread voter fraud involving mail-in ballots. He has repeatedly described his 2020 election defeat as “rigged,” pointing to expanded mail-in balloting that was allowed during the coronavirus pandemic.

Experts have repeatedly said there is very little fraud connected to mail-in voting and that there are safeguards in place to prevent fraud. Colorado is one of eight states that conducts universal mail-in voting where all residents are automatically sent a mail-in ballot.

Trump in March signed an executive order that would dramatically overhaul how federal elections are run, a move that follows years of exaggerated claims from Trump about mail ballots and noncitizen voting.
