(CNN) - Elon Musk’s pro-Trump Super PAC awarded its final $1 million prize to a registered voter in Michigan. It brings an end to the daily sweepstakes, which attracted both federal and state-level legal scrutiny.

Elon Musk was sued in a proposed class action on Tuesday by registered voters who signed his petition to support the Constitution for a chance to win his $1 million-a-day giveaway, and now claim it was a fraud.

A group of lawyers who served in Republican administrations contacted the DOJ about the legality of America PAC's $1 million giveaway, prompting the agency to write to Musk's PAC.

Musk said he'd give $1 million to random voters in swing states like Nevada who signed his petition. The justice department said it might not be legal.

Elon Musk's pro-Trump group does not choose the winners of its $1 million-a-day giveaway to registered voters at random, but instead picks people who would be good spokespeople for its agenda, a lawyer for the billionaire said on Monday.

Elon Musk’s lawyer told a Pennsylvania judge that the winners of a million-dollar voter giveaway were chosen “not by chance.”
