The Supreme Court on Monday handed the Trump administration a victory, allowing it to enforce President Donald Trump’s “election integrity” executive order restricting mail-in voting ahead of the November midterms. 

The high court lifted an injunction that had blocked the order in 23 states that challenged it after the administration appealed in July; Justices Sonia Sotomayor, Elena Kagan and Ketanji Brown Jackson dissented. 

The U.S. Postal Service and Justice Department said they would immediately implement the revised mail-ballot restrictions after the ruling.

The decision appears to leave room for additional court challenges that could further slow Trump’s order.
