Gov. Gavin Newsom, in a preemptive strike against President Donald Trump, said Wednesday he plans to sue Trump’s administration to block a controversial plan to increase water deliveries to the San Joaquin Valley.

Newsom’s office said he “will file legal action in the coming days … to protect highly imperiled fish species close to extinction.”

The announcement came just minutes before Trump appeared in Bakersfield to announce he’s finalized an order removing regulatory roadblocks and enabling the giant Sacramento-San Joaquin Delta pumps to deliver additional water to the southern half of the state.
