Immigration and Customs Enforcement officers obtained individual voter files in Texas this spring and North Carolina last November as part of the Trump administration’s effort to identify instances of voting by illegal immigrants.

Voter files from Webb County and Forsyth County were shared with Department of Homeland Security Investigations agents, according to emails obtained through Democracy Forward records requests shared with Axios. The report comes as the SAVE Act, which requires voters to provide proof of citizenship to register to vote in federal elections, has stalled in the Senate despite President Donald Trump’s push to advance the measure.
