Michigan Congressman John Conyers is running for re-election this year. He needs 1,000 signatures to get on the Democratic primary ballot. Two of his petitioners were apparently not registered voters when they circulated his petition, and the Conyers campaign will probably file a lawsuit to overturn the Michigan law that requires circulators to be registered voters.
On May 8, law enforcement officials confirmed that one of the two circulators is wanted for probation violations in Battle Creek. See this story.
