WATCH: How Trump’s economic policies could shape the midterms

The Trump administration has issued over 100 subpoenas capturing records of thousands of voters across at least 13 states, intensifying its pursuit of evidence of illegal voting by noncitizens ahead of the upcoming midterm elections, as revealed by Reuters through public-records requests and discussions with local and state officials.

Most of these subpoenas were issued to state and local election officials in the last three months, though some originated as early as the beginning of the year. These records, many of which have not been previously reported, indicate a federal campaign to pinpoint potential noncitizen voters that extends beyond what was previously acknowledged.

It is against the law for noncitizens to cast ballots in US federal elections. Legal authorities contend that these documents could potentially be utilized to challenge results in closely contested midterm races, despite the lack of substantial proof suggesting widespread noncitizen voting. The subpoenas have been issued in Democratic strongholds such as Minneapolis, Philadelphia, Los Angeles, and various other cities in California, but also extend to Republican-leaning states where competitive races are anticipated.
