More than 3,000 Alaska voters have been asked to verify their U.S. citizenship ahead of next month’s primary election, an unusually large number that has drawn scrutiny from lawmakers amid a broader push by the Trump administration for states to strengthen citizenship checks before the 2026 midterm elections.

The Alaska Division of Elections said it mailed about 3,048 letters to registered voters asking them to confirm their U.S. citizenship before the Aug. 18 primaries. Election officials said the number is significantly higher than the roughly 200 voters typically flagged during routine voter roll maintenance and may be the result of outdated information in the state Division of Motor Vehicles records.
