The district runs from the L.A. suburbs to Palm Springs and in the video the musician said, “Ken Calvert has been in Washington for 30 years and all he’s done is make himself millions,” said over footage including a headline reading “Ethics Complaints Filed Against California GOP Rep.

In the fight for the U.S. House, Democrats are hoping pop rock star power will help oust a long-serving Republican east of Los Angeles as the party looks to regain control of the chamber and slow President Donald Trump’s agenda. Tim Myers, a Grammy-nominated former bassist for international hitmakers OneRepublic, announced Thursday he will challenge Rep. Ken Calvert in the battleground 41st District in Riverside County that stretches from the L.A. suburbs to the resort haven of Palm Springs.

Christian Martinez, a spokesperson for the campaign arm of House Republicans, said in a statement that “Democrat Tim Myers is everything wrong with today’s radical left: a Hollywood liberal trying to fake his way into Riverside County.”
