Veteran California US House member Mike Thompson will face Democratic challenger in November

Mike Thompson, a California U.S. House member, will face Eric Jones in November in a Democratic primary for the state’s 4th Congressional District. Jones advanced to the November ballot after a June 2 primary, marking a generational challenge within the party.
