Elon Musk was sued by the Philadelphia district attorney over his political action committee’s $1 million a day sweepstakes targeting swing state voters in the final days of the U.S. presidential election.

The DA, Larry Krasner, is asking a state court to stop Musk from engaging in an “unlawful lottery,” which lulls “Philadelphia citizens to give up their personal identifying information and make a political pledge in exchange for the chance to win $1 million.”
