President Donald Trump has signed another sweeping executive order that this time could dramatically change how elections are run across the country. The order targets mail-in voting and citizenship verification—two key components that could impact millions of voters.

Under the new order, states would be required to reject ballots not received by Election Day, and the Justice Department would be directed to enforce the rule. Trump has routinely criticized mail-in voting, and voting rights experts warn this change could disproportionately affect low-income and minority voters.

It also demands that the Election Assistance Commission add proof of citizenship to voter registration forms — a move that many argue could suppress votes, as these requirements are often difficult for marginalized communities to meet.

Election law experts question the legality of the order, with some arguing Trump doesn’t have the authority to enforce such sweeping changes.
