The DOJ Civil Rights Division under Assistant Attorney General Harmeet Dhillon sent letters to election officials in at least six states, including Nevada, Arizona, and Colorado, warning of criminal penalties for failing to prevent noncitizen voting under federal law. ABC News reported that one recipient described the letters as threatening and noted the division's prioritization of the issue. A 2017 Brennan Center study cited in the coverage found noncitizen voting accounted for 0.0001% of votes in 42 jurisdictions during the 2016 election.
