Trump signs order to make voters show proof of citizenship in elections, with swift pushback expected from states which set their own voting rules

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.

The order says the U.S. has failed “to enforce basic and necessary election protections” and 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.
