US Supreme Court allows Trump mail-in voting restrictions to proceed

Washington, August 25, 2026 — The US Supreme Court has allowed the Trump administration to implement part of an executive order tightening mail-in voting rules. The 6-3 decision permits Homeland Security to compile lists of US citizens eligible to vote on a state-by-state basis and to provide those lists to the states.

Election officials in several states have said there is no practical way to implement the full set of changes before the November midterms if lower courts do not intervene further. The ruling leaves the ultimate legality of the broader executive order unresolved.

The administration argues the measures are needed to protect election integrity. Opponents say they risk suppressing legitimate votes and place an unworkable burden on state election systems so close to voting day.

The decision forms part of a larger pattern of legal contests over voting procedures. States that rely heavily on mail ballots will now have to decide how far to integrate the new federal lists into their existing processes.

Further litigation is expected. For election administrators the immediate task is to assess what can realistically be done in the remaining weeks before early voting begins. For the campaigns the ruling adds another layer of uncertainty to an already contested electoral landscape.
