SAN DIEGO (AP) — Hundreds of thousands of dollars in illegal campaign contributions from a wealthy Mexican businessman supported San Diego politicians, according to a federal complaint unsealed Tuesday.

The businessman has homes in California but is not a U.S. citizen or legal resident, making it illegal for him to donate to campaigns, the complaint says. He has not been charged and isn’t named in the complaint, but two alleged associates and a company are charged with conspiracy to commit offenses against the United States.
