UPDATED: Trump administration says DHS is investigating alleged noncitizen voting cases and has made 151 voter-fraud arrests in the United States

The Trump administration said in the United States that the Department of Homeland Security is investigating 1,620 alleged cases of noncitizens casting ballots and has made 151 arrests. DHS chief Markwayne Mullin said the department is comparing voter records against federal immigration databases and may review as many as 300,000 additional cases; the article also cites an earlier administration plan allowing states to verify voter citizenship through federal databases and support Justice Department reviews under federal election laws.
Why it matters: The development links immigration records to voter-roll enforcement and could affect registered voters, legal permanent residents, and state election administration. Supporters say it is needed to protect election integrity, while critics are likely to scrutinize the evidence for the claims and the risk of wrongful removals or investigations.
