After spending years making false claims about election fraud and rampant non-citizen voting, Trump issued an executive order Tuesday imposing "proof of citizenship" requirements for voters.

In an attempt to buckle down on election crimes, President Trump threatens to withdraw federal funding from states that do not comply with his executive order.

President Donald Trump on Tuesday signed a sweeping executive action to overhaul elections in the U.S., including requiring documentary proof of citizenship to register to vote in federal elections and demanding that all ballots be received by Election Day.
