A state bill that would prohibit state law enforcement from cooperating with federal immigration enforcement was approved Mon to reach the Ca. State Senate.

If passed, Senate Bill 54, or SB 54 — also known as the Cal. Values Act — will prohibit law enforcement agencies, including school police, from using public resources to “investigate, interrogate, detain, detect, or arrest persons for immigration enforcement purposes,” according to the bill text. The bill was introduced by Sen. Kevin de León and co-authored by Sen. Toni Atkins, Sen. Richard Pan and Sen. Scott Wiener.
