Trump signs second election executive order directing USPS to block mail ballots to non-verified voters

President Trump signs a second election executive order on March 31, 2026, directing the Department of Homeland Security and the Social Security Administration to compile "State Citizenship Lists" of eligible voters in each state and instructing the U.S. Postal Service to refuse to deliver mail ballots to anyone not on those lists. The order also directs the USPS to create trackable barcodes on all mail ballot envelopes and authorizes Attorney General Pam Bondi to investigate and prosecute election officials who send ballots to ineligible voters. Trump describes the order as "foolproof" at the signing ceremony. Election law scholars across the political spectrum immediately criticize the order as unconstitutional, noting that the Elections Clause gives Congress — not the president — authority over federal election rules, and that USPS is an independent agency whose operations Congress controls by statute.
