Thirty House Democrats have sent a letter to Postmaster General David Steiner demanding answers about whether the U.S. Postal Service was pressured by the Trump administration to interfere with mail-in ballot delivery ahead of the 2026 elections, and about a newly proposed federal rule that would attach conditions to how mail-in ballots are accepted. The letter, and the questions in it, were reported by Black Star News, drawing on a press release from the office of Rep. Kweisi Mfume.
