The Supreme Court upheld President Trump's mail-in ballot executive order, stating that states that sued to block it acted too early to prove harm would result.

Twenty-three states and Washington D.C. sued to block mail-in ballot executive order

USPS develops new mail ballot screening system using barcode verification
The U.S. Postal Service created a new system requiring states to report voter information attached to unique barcodes on mail-in ballots.

Anonymous USPS whistleblower reports catastrophic failures in ballot system development
An anonymous government employee whistleblower warned that USPS's effort to implement the new mail-in ballot system is "rushed, chaotic and fundamentally flawed" with "potentially catastrophic problems."

Trump administration appeals federal court decision blocking mail voting restrictions
The Trump administration filed a notice of appeal on Friday challenging a federal judge's ruling that blocked implementation of an executive order limiting mail voting before the midterm elections.

Supreme Court allowed mail voting order to proceed on procedural grounds without ruling on legality

Trump executive order restricts mail ballot delivery based on voter list and envelope requirements

A coalition of 23 Democratic-led states, the District of Columbia, Pennsylvania Governor Josh Shapiro, and voting rights organizations including the League of Women Voters filed lawsuits challenging the USPS mail-in voting rule.
