Gov. Josh Shapiro has serious concerns about billionaire Elon Musk's multi-million dollar donation to registered voters, which an expert says is “clearly illegal.”

Musk has vowed to give away $1 million every day to a randomly selected battleground state that signs his conservative-leaning petition urging registered Republicans to vote. He presented the first check on Saturday at his America PAC event in Harrisburg, Pennsylvania, to a signatory of his “Petition for Free Speech and the Right to Bear Arms.” Musk also promises money to those who refer other registered voters to sign the petition. “As a thank you for your support, you will receive $47 for each registered voter you refer who signs this petition,” the petition reads.

But Shapiro has serious doubts about the legitimacy of Musk's enticements.

“I think there are real questions about how he's spending money in this race, how the dark money is flowing not only into Pennsylvania but apparently now into the pockets of Pennsylvanians,” Shapiro said Sunday Meet the press. “This is deeply worrying. Look, Musk obviously has the right to express his views. He's made it very, very clear that he supports Donald Trump. Not me – obviously we have different opinions. I do not deny him this right. But when you start pouring that kind of money into politics, I think it raises serious questions that maybe people should start looking at.”

“So you think it might not be legal, yes or no?” Welker asked.

“I think this is something that law enforcement could look at,” Shapiro said. “I am no longer the attorney general of Pennsylvania. I’m the governor, but it raises some serious questions.”

According to a Justice Department handbook on election crimes, it is illegal to pay citizens with the intent of getting them to vote or register to vote. It prohibits the enticement of votes or registrations with cash, but also with anything of monetary value, including lottery chances. However, since Musk is paying people to sign his petition, he may be trying to circumvent these laws.

But Rick Hasen, a political science professor and director of the Safeguarding Democracy Project at the UCLA School of Law, said in a post on the Election Law Blog that Musk's actions may be illegal because eligibility to win the million is contingent on registering to vote .

“The only petition signers eligible to participate in Elon Musk’s $1 million lottery are those who are eligible to vote. So it is an illegal incentive to register or a reward for registering. Both are illegal,” Hansen wrote on X.
