LOS ANGELES — President Donald Trump returns to California on Friday for a trip to the U.S.-Mexico border and a fundraiser in Los Angeles as the state's Republican Party struggles on many fronts.

"The Republican Party has been a bad brand name in California politics for a decade, and I think Donald Trump made it a toxic brand," said Thad Kousser, political science chair at the University of California, San Diego. "The clearest flash point for this is in immigration and also the environment."
