President Donald Trump has been relentless in trying to rewrite the rules of American elections, but the U.S. Supreme Court has issued a ruling rejecting his effort to use the United States Postal Service (USPS) as a tool to sow electoral confusion and chaos.
In March 2026, after President Trump issued an executive order directing USPS to change how they process and distribute mail ballots, multiple pro-democracy groups, including Campaign Legal Center (CLC), sued to prevent the order from going into effect.
The executive order sparked a long-winding legal battle with multiple lawsuits across the country challenging USPS’ attempts to comply with the president’s unlawful actions.
After a federal court in Massachusetts blocked the USPS’s new regulations that aimed to implement the president’s illegal command; the Trump administration asked the Supreme Court to block that court order and allow USPS to enforce its new rules.
Campaign Legal Center alongside its co-counsel, Democracy Defenders Fund, on behalf of our clients the League of United Latin American Citizens (LULAC), Arizona Students' Association (ASA), Secure Families Initiative (SFI), the city of Madison, Wisconsin, and Travis County, Texas, filed an amicus brief urging the Court to reject the government’s request and keep the order blocking USPS’s rules in place.
On September 14, 2026, the Supreme Court issued an order denying the government’s request to stay the order blocking the USPS rule — which means that USPS cannot mandate compliance with its rule for the 2026 midterm elections.

Now, voters can continue to confidently vote by mail in the 2026 midterm elections, just as they have done for over a century.
This executive order was just another attempt by the Trump administration to unlawfully exert control over our federal elections. The president’s efforts to limit access to mail-in voting — even though voting by mail is a safe, secure and accessible method of voting that the president himself regularly uses — have been thwarted thanks to pro-democracy organizations across the country, including CLC.
Attempting to restrict millions of Americans’ freedom to vote through an executive order is an unconstitutional and illegal abuse of executive power. Furthermore, independent agencies like USPS are meant to function autonomously to serve the American people, not the president’s political interests.
Voting by mail effectively expands access to the ballot for more voters, which strengthens our democracy.
Campaign Legal Center is proud to have played a part in this important victory, and we’ll continue to fight to ensure all voters can make their voices heard in this election, and future elections to come. Join us today.
