Trump admin. suing California over sanctuary laws

• Homeland Security Secretary Kirstjen Nielsen said: "California has chosen to purposefully contradict the will and the responsibility of the Congress to protect our homeland .... I appreciate the efforts of Attorney General Sessions and the Department of Justice to uphold the rule of law and protect American communities.”
• Per Politico, the three laws the lawsuit mentions, are:
• SB 54 — which keeps state and local officials from "sharing information with immigration authorities under certain circumstances and...bars transfers of certain immigrations to federal custody."
• AB 450 — keeping private employers "from cooperating with federal immigration enforcement at the workplace."
• AB 103 — seeking "to regulate contract detention facilities used to hold federal immigration prisoners."

What to watch for: Per Politico, Attorney General Jeff Sessions is going to California on Friday, to "tout the new lawsuit...in a speech to law enforcement officials."
