The Supreme Court blocked President Donald Trump's mail-in voting order on Monday, allowing a lower court's ruling to remain in effect.

The ruling, which marked a major blow to the Trump administration, blocked proposed changes to the United States Postal Service that would require states to submit mail-in voter lists to the service. The service would then refuse delivery of ballots to recipients not on the list.

The majority of justices determined that the administration's position was unlikely to succeed, while Supreme Court Justice Brett Kavanaugh said in a separate opinion that “state and local election officials do not have sufficient time to reasonably implement the rule before the election.”

Justices Clarence Thomas and Samuel Alito dissented.
