President Donald Trump on Tuesday signed a sweeping executive action to overhaul U.S. elections, including requiring documentary proof of citizenship to register to vote in federal elections and demanding that all ballots be received by Election Day. The order calls on states to work with federal agencies to share voter lists and prosecute election crimes. It threatens to pull federal funding from states where election officials don’t comply.

Trump often claims elections are being rigged, even before the results are known, and has waged battles against certain voting methods since he lost the 2020 election to Democrat Joe Biden and falsely blamed it on widespread fraud.
