The North Carolina Attorney General’s Office said Monday that it is eyeing a political action committee created by billionaire Elon Muskfollowing a complaint to the state election board over the PAC’s collection of personal data while failing to help users register to vote as promised.

The North Carolina Board of Elections later Monday told CNBC that it has opened an investigation of Musk’s America PAC.

“North Carolina law makes it a crime for someone to fail to submit a voter’s registration form if that person has told a voter that they would be submitting the voter’s registration form,” the board’s spokesman, Patrick Gannon, told CNBC.

The new inquiries and a similar one announced Sunday by Michigan’s secretary of state’s office follow a report by CNBC that Musk’s America PAC was asking website users in battleground states for personal data — such as ZIP code, full address and a phone number — under the pretext of helping them register to vote without doing so.
