Court filing disputes Trump administration list of alleged non-citizen voters in California

A new court filing has raised further doubts about the accuracy of a list of so-called likely non-citizen voters that the Trump administration sent to California ahead of the midterm elections.

On Saturday, the advocacy group Coalition for Humane Immigrant Rights (CHIRLA) submitted to the court an analysis carried out by two data scientists from the University of California, Los Angeles. The analysis found that more than four in every ten names on the list did not appear on California's voter rolls at all. It also found that thousands of potentially eligible US citizens had been wrongly flagged as ineligible to vote.

The list, handed to California by the Trump administration in early October, had claimed that up to 20,930 likely non-citizens were registered to vote in the state. That list underpins a lawsuit filed on October 15 seeking to have California set aside any ballots cast by those named, so they would not be counted in the results.

The legal dispute is playing out just days before Tuesday's midterm elections, which will determine control of both chambers of the US Congress as well as numerous state and local offices. President Trump has previously said he fears impeachment should Republicans lose their congressional majorities.
