Elon Musk‘s political action committee received a warning from the Department of Justice that the $1 million giveaway he is offering in battleground states ahead of the 2024 election could be illegal, according to a new report.

The DOJ wrote the warning letter to Musk’s organization sometime in the last few days, according to CNN. The revelation came after the tech billionaire announced on Saturday while stumping for Trump at an event in Pennsylvania that he would give away $1 million to random voters who signed his super PAC’s petition in support of constitutional freedoms.
