What the official said
“they caught thousands of votes in New Jersey where illegal aliens were allowed to vote”
Claimant: Donald J. Trump President of the United States
Agency or office: Executive Office of the President
Context
New Jersey announced a software error that led to 6,600 noncitizen registrations being added to voter rolls; the state's preliminary review found up to 400 votes cast by noncitizens. DHS later released a separate, disputed figure (35,152 registered noncitizens in New Jersey) but did not provide underlying methodology; experts warn such automated matches can create many false positives.
Evidence
The president's claim that 'thousands' of votes were cast by noncitizens in New Jersey is not supported by the state's preliminary investigation, which identified up to about 400 votes cast by noncitizens — far fewer than 'thousands.' The 6,600 figure refers to improperly added registrations, not votes cast. A separate DHS estimate (35,152 registered noncitizens in New Jersey) has not been substantiated with methodology and has been questioned by state officials and election experts as likely to include many false matches. Even if the higher counts were accurate, the number of verified noncitizen votes identified so far is too small to have altered New Jersey's statewide federal election outcomes.
