The U.S. Department of Justice (DOJ) sued Connecticut and the City of New Haven on April 13 over policies limiting cooperation with federal immigration enforcement.
The DOJ challenged Connecticut’s Trust Act and an executive order issued by New Haven’s mayor, arguing that they conflicted with federal immigration law and the Constitution. Specifically, the DOJ alleged violations of the U.S. Constitution’s Supremacy Clause, which says federal law takes precedence over state and local laws.
