Trump Signs Election Integrity EO: DHS to Compile State Voter Citizenship Lists, USPS Ballot Restrictions

President Trump signed an executive order on April 1, 2026 directing DHS — in coordination with the Social Security Administration — to compile a State Citizenship List of confirmed US citizens eligible to vote in each state. The order further directs USPS to transmit ballots only to individuals on a state-specific Mail-in and Absentee Participation List. States that do not comply with the federal citizenship verification framework face threats of withheld federal funds. The order was framed by the White House as an 'election integrity' measure preventing non-citizens from voting, though federal prosecutors and election law experts noted no documented evidence of widespread non-citizen voting in recent elections. Democrats immediately vowed legal challenges, with the ACLU calling it a backdoor attempt to establish a federal voter registry. Civil liberties groups raised concerns that the cross-referencing of SSA and DHS databases would produce high rates of false negatives, potentially disenfranchising millions of eligible voters — particularly naturalized citizens and those whose SSA records contain clerical errors.
