Trump signs EO 14399 directing DHS to obtain voter rolls and restricting USPS mail ballot delivery

President Trump signed Executive Order 14399 on March 25, 2026, directing DHS to obtain state voter rolls and cross-reference them with federal immigration databases, and ordering USPS to restrict delivery of mail ballots not matching verified DHS addresses. Election law scholars immediately argued the cited statutes — HAVA and the NVRA — do not authorize executive agencies to restrict ballot delivery. At least eight civil rights organizations filed suit within 72 hours.
