The claim is true because multiple reliable sources confirm that Alaska recently removed about 3,000 to 3,500 voters from its active voter rolls due to citizenship concerns, requiring those individuals to verify their citizenship to regain active status, and this action followed New Jersey's discovery of thousands of noncitizens registered to vote due to a DMV software error.
Alaska has suddenly removed THOUSANDS of noncitizens from their voter rolls, after New Jersey also caught thousands were registered. Several thousand people must now prove citizenship if they want to be re-added.

What the Evidence Shows
Several independent and reputable news outlets report that the state of Alaska has moved approximately 3,000 to 3,500 registered voters to an inactive status after flagging them as potential noncitizens. These voters must now provide proof of citizenship if they want to be reactivated on the voter rolls. The Alaska Division of Elections used data that included some outdated DMV records, which led to some eligible citizens being erroneously flagged. This process is part of a broader effort influenced by federal pressure and precedes upcoming elections.
Separately, New Jersey identified over 6,000 noncitizens who were mistakenly registered to vote due to a software error at the state's Motor Vehicles Commission. This discovery has prompted increased scrutiny and verification efforts in other states, including Alaska.
The sources consistently indicate that while thousands were flagged and removed or made inactive, some eligible voters were mistakenly affected due to reliance on old or inaccurate data. Alaska has sent letters to these voters requesting citizenship verification. The linkage between New Jersey's incident and Alaska's actions is noted in several reports as part of a national context of voter roll maintenance and citizenship verification efforts.
Overall, the claim accurately reflects the scale (thousands), the states involved (Alaska and New Jersey), and the requirement for affected voters to prove citizenship for reactivation.
