Legal expert explains Supreme Court's decision to block Trump's mail-in voting rules

As the US Supreme Court blocked President Donald Trump's attempts to make mail-in voting more restrictive for the midterms, election officials across the nation are intensifying their efforts to assure Americans that casting ballots by mail remains safe and secure. The court's ruling on Monday, which infuriated Trump on his Truth Social platform, effectively thwarted a plan that election officials from both parties feared could have turned this year's elections into an administrative nightmare.

The high court's decision came just in time to prevent a cascade of problems that Trump's order would have triggered. The president had demanded the redesign of mail-in envelopes and the upload of voter lists to the United States Postal Service (USPS), measures that election officials warned would be impractical and unworkable before ballots were already in circulation. This development was viewed by many as an attempt by the administration to alter voting policies and undermine trust in the integrity of mail-in ballots.
