On Tuesday, March 31, 2026, Trump signed an executive order aimed at building voter-eligibility lists using federal data and tying USPS mail-ballot delivery to those lists.
The order directs the Department of Homeland Security to create âstate citizenship listsâ using federal citizenship/naturalization records, Social Security records, and other federal databases.
The order contemplates sending these lists to states to help verify voter rolls.
The order also asks USPS to transmit mail ballots only to people addressed on those citizenship lists, effectively pushing USPS into an election-eligibility screening role.
NBC News reports the order is expected to be challenged quickly, citing the Constitutionâs allocation of election rulemaking primarily to states (with some authority for Congress).
Election administration experts quoted by NBC News predict courts will deem the order unconstitutional or block it swiftly.
NBC News notes internal involvement by Kurt Olsen (White House election security and integrity director) and Heather Honey (DHS senior role), both connected to post-2020 election efforts.
The article points to Trumpâs continued false claim that he won the 2020 election as background for why he is pursuing mail-voting restrictions and federalized election policy.
NBC News notes a prior Trump election-related executive order (from March 2025) had many provisions blocked by courts, suggesting similar legal vulnerability for this order.
The piece situates the order alongside Trumpâs push for the SAVE Act, which would impose proof-of-citizenship requirements through legislation but has faced a higher bar in the Senate. ([congress.gov](https://www.congress.gov/bill/119th-congress/house-bill/22))
