Twenty-three U.S. states and the District of Columbia have sued to block President Trump’s 2026 executive order imposing new federal requirements on mail-in voting.

The statement correctly identifies a lawsuit brought by officials from 23 states and the District of Columbia against President Donald Trump’s executive order concerning mail voting. The case challenged provisions that would establish additional federal restrictions on the processing and use of mail ballots during the 2026 midterm elections. CBS News reported the filing on April 4, 2026, and subsequent coverage confirmed that the same coalition remained involved.cbsnews.comcbsnews.com23 states sue Trump over new executive order targeting mail votingusnews.comusnews.comDemocratic-Led States Renew Challenge to Trump Plans to Restrict Mail-In Voting

The case’s procedural status later shifted. Although a federal judge had temporarily barred enforcement in the states involved, the Supreme Court subsequently suspended that injunction, permitting significant parts of the order to move forward as the wider dispute continues. This does not undermine the statement that the states and the District of Columbia sued to stop the order, but it does show that the litigation has not produced a lasting block on its implementation.pbs.orgpbs.orgSupreme Court clears the way for Trump mail voting order ahead of midtermscbsnews.comcbsnews.comSupreme Court allows Trump to implement key parts of order restricting mail...+2 more

The coalition has continued to contest the order. Coverage dated August 26, 2026, refers to a new or renewed action brought by Democratic-led states following the Supreme Court’s decision. The reports vary somewhat in their descriptions of the procedural step and the parties, including the roles of Pennsylvania’s governor and Maine, but consistently describe 23 states and the District of Columbia as participants in the challenge.pbs.orgpbs.orgDemocratic states file new lawsuit seeking to block Trump's order limiting mail...usnews.comusnews.comDemocratic-Led States Renew Challenge to Trump Plans to Restrict Mail-In Voting+2 more

Describing the order as “imposing” requirements is a fair characterization of a measure intended to limit mail voting, although both its operation and legality remain disputed. The Supreme Court’s interim action allowed important provisions to operate; it did not conclusively uphold every part of the order. The core claim, that 23 states and the District of Columbia sued to block it, is supported by the available coverage.
