The Supreme Court rejected President Donald Trump's challenge to state laws allowing mail ballots postmarked by Election Day to be counted after Election Day.
Despite the ruling, the court simultaneously issued its decision in Trump v. Slaughter, overturning nearly a century of precedent by allowing the president to fire members of independent agencies without cause.
Reuters' White House correspondent Jacob Bogage explained the ruling's implications on X, "This also has big potential mail-in voting consequences," he wrote.
"It could empower the president to fire members of the USPS board of governors, the group that selects the postmaster general and overseas the U.S. mail system."
Current Postmaster General David Steiner is already implementing a controversial Trump executive order directing the Postal Service to withhold mail ballot delivery in states refusing to provide sensitive voter practice information to the federal government.
A federal judge in Boston has moved to block enforcement of the executive order, though litigation is expected to continue.
