What to know about the Trump administration's claim that 250K non-citizens are registered to vote in 4 states

Key Points:

• Homeland Security Secretary Markwayne Mullin supported President Trump's claim that over 250,000 non-citizens are registered to vote in California, Pennsylvania, New Jersey, and Nevada, though no detailed methodology has been provided by the administration.
• Experts and election officials have criticized the claim, noting that the estimate is likely inflated due to reliance on commercial databases prone to false positives, and confirmed cases of non-citizen voting remain exceedingly rare.
• The four states named have largely rejected the allegations, with officials emphasizing that voter rolls are properly maintained and expressing skepticism about the administration’s data and methods.
• Several states that conducted audits found only small numbers of non-citizens registered to vote, representing a tiny fraction of their total voter rolls, far less than the Trump administration’s claims.
• The Trump administration has pursued legal and administrative measures to tighten voting regulations, including executive orders and lawsuits to obtain voter data, though many of these efforts have faced court challenges and resistance from states.
