WASHINGTON (AP) — The Trump administration asked the Supreme Court on Monday to clear the way for an executive order from President Donald Trump that could dramatically change mail-in voting ahead of November’s midterm elections.

The Justice Department asked the justices to halt for now lower court decisions blocking the sweeping changes in nearly half the country.

The request comes shortly after Trump delivered a primetime address elevating his yearslong push to raise doubts about the legitimacy of elections, and could be one of several voting-related challenges before the court ahead of the high-stakes midterm contest.
