Not all of California opposes President Donald Trump's immigration policies.

Los Alamitos, a small city in Orange County, voted last week to oppose California's "sanctuary" law. And now the county government is joining the backlash against the state policy, which prohibits local law enforcement from some cooperation with federal immigration enforcement, reports CNN.

The Orange County Board of Supervisors voted Tuesday in a closed-door session to join the federal government in a lawsuit against California over the state law that went into effect in January.

Earlier this month, US Attorney General Jeff Sessions announced a lawsuit over California's sanctuary policies in an escalating battle between the Trump administration and the Golden State. The lawsuit is over parts of three California laws that are intended to protect undocumented immigrants from federal immigration officials.
