Trump administration files emergency Supreme Court appeal to enforce mail-in voting restrictions

Background

President Donald Trump signed an executive order in March 2026 that directed the Department of Homeland Security and the Social Security Administration to compile state-by-state lists of eligible voters. The order also required the U.S. Postal Service to deliver mail ballots only to individuals appearing on those lists, and instructed the Justice Department to prioritize investigations and prosecutions of election officials who issue ballots to people deemed ineligible. Trump promoted the measures as safeguards against non-citizen voting, though studies have repeatedly shown such fraud is rare and is already a felony punishable by deportation.

Lower court rulings

Democratic officials from 23 states and the District of Columbia sued in federal court in Boston, arguing that the Constitution gives states and Congress the authority to set election rules, not the president. In June, U.S. District Judge Indira Talwani blocked key parts of the order for those plaintiff states, writing that "the Constitution does not grant the President any specific powers over elections." Over the weekend, a divided three-judge panel of the First U.S. Circuit Court of Appeals upheld that block. The majority, consisting of judges appointed by Joe Biden and George W. Bush, found that the order would "sow confusion" and "threaten disenfranchisement of many eligible voters." A Trump appointee dissented.

Supreme Court appeal

On Monday, the Justice Department filed an emergency application asking the Supreme Court to pause the lower court ruling while the legal challenges proceed. Solicitor General D. John Sauer argued that the injunction is causing "serious irreparable harm on the federal government" and called it "indefensible."

The injunction is especially indefensible because the agencies are still deliberating over how (if at all) to implement the Order, yet the district court preemptively decided that whatever the agencies may choose to do will necessarily be unlawful.

The administration characterized the order as "general policy guidance" rather than a directive dictating state election administration. Sauer urged the justices to act quickly, noting that any new policy would need to be in place by August to be effective for the November midterms. The Supreme Court has asked the challenger states to respond by Monday, August 3.

Political stakes

Trump has for years made unfounded claims that mail-in voting is rife with fraud, including false assertions about the 2020 election. He has vowed to end the widespread use of mail ballots before the midterms, which will determine control of both the House of Representatives and the Senate. Voting rights advocates note that restricting mail-in voting could disproportionately affect Democratic voters, who have historically been more likely to vote by mail. Trump is simultaneously pressing the Republican-controlled Congress to pass the SAVE America Act, which would require proof of citizenship to register to vote, among other restrictions.

What's next

The Supreme Court will consider the emergency application after receiving responses from the challenger states. If the justices grant the administration's request, federal agencies could begin implementing the executive order in the 23 states and Washington, D.C., potentially reshaping mail-in voting rules just months before the November 3 elections. A denial would leave the lower court block in place while the full legal challenge continues.
