Trump signs second federal-elections executive order asserting presidential control over voter eligibility and mail voting
On March 31, 2026, President Donald Trump signed Executive Order 14399, "Ensuring Citizenship Verification and Integrity in Federal Elections," directing the Department of Homeland Security and Social Security Administration to compile federal "citizenship verification" lists and instructing the U.S. Postal Service to deliver mail ballots only to voters on those lists. Constitutional law experts, federal courts, and 24 state attorneys general have stated that the president has no authority under the Elections Clause (Art. I, Sec. 4) to set federal voting procedures — a position that already produced a 2025 injunction against substantial portions of Trump's first elections executive order.
