Mississippi Closed the Holes in Its Own Sanctuary-City Ban.

What good is a law banning sanctuary cities if a city can still find a way around it?

Mississippi already had a sanctuary-policy ban on the books. HB538 closes the holes in it.

The bill broadens the statute's coverage to any government policy, order, ordinance, practice, or procedure, at any level: state, county, municipal, or public higher education. It adds a mandatory-cooperation duty covering ICE detainer requests, meaning local jails have to hold someone federal immigration agents have flagged rather than release them first. And it creates a real enforcement mechanism at the Attorney General's office, with investigatory power and the authority to seek an injunction against officials who don't comply. The bill also removes sovereign immunity protection for entities that violate it.

Rep. Lee Yancey authored the bill. Sen. Jeremy England, who carried it in the Senate, put the argument plainly: "We don't want any of this sanctuary city type of business." England's position is that federal immigration agents should be able to do their jobs "without interference from Mississippians."

Cooperation duties like this one raise a real question critics have pressed in other states: what happens when the federal agents being cooperated with make a mistake, or worse. In Minnesota, American citizens Renee Goode and Alex Pretti were fatally shot by immigration agents in cases that became national flashpoints for exactly that concern. England has acknowledged he doesn't want the state investigating federal misconduct itself. His answer is that the priority is enforcement and cooperation, not oversight of the agents doing the enforcing.

That's not an oversight in the bill. It's a deliberate choice about what this law is and isn't for. HB538 compels state and local cooperation with federal immigration law. It does not create a state mechanism to police how federal agents conduct themselves once that cooperation happens.

The final conference report cleared the Senate 36-16 and the House 76-39 on March 31, 2026. Governor Reeves signed it April 8, 2026, effective July 1.

Mississippi didn't write a new sanctuary-city ban. It fixed the enforcement holes in the one it already had, gave the Attorney General real teeth, and made clear where state responsibility ends and federal responsibility begins.
