1. There’s going to be a showdown in California.

President Trump is there for fund-raisers in Los Angeles and Silicon Valley on Wednesday — when his administration plans to strip California of the authority to set its own auto pollution rules.

The move’s been expected since last year, when the Environmental Protection Agency and the Transportation Department unveiled plans to roll back the Obama administration’s strict federal fuel-economy standards. California intends to keep them. Expect a fight.

“California will continue its advance toward a cleaner future,” said Xavier Becerra, the state attorney general. “We’re prepared to defend the standards that make that promise a reality.”
