(FOX NEWS) — Washington Attorney General Nick Brown is suing a county sheriff’s office in his state for “illegally collaborating” with federal officials and the Trump administration to enforce immigration law.

Brown’s lawsuit, which was filed in Spokane County Superior Court, claims that the Adams County Sheriff’s Office’s holding of illegal immigrants in custody based on their immigration status, helping federal agents question people in custody and “routinely” sharing personal confidential information of Washington residents with federal officials “expressly violates state law.”

The suit cites a 2019 law called the Keep Washington Working Act, which prohibits law enforcement in the state from providing aid in immigration enforcement. Brown is asking the court to force the Adams County Sheriff’s Office, led by Sheriff Dale Wagner, to comply with the Keep Washington Working Act.
