DENVER (AP) 鈥 The Department of Justice sued Colorado and Denver on Friday for allegedly interfering with federal efforts to enforce immigration laws, the latest attempt by the Trump administration to crack down on what some call sanctuary cities and policies.
The lawsuit claims the state and its most populous city, Denver, have passed 鈥渟anctuary laws鈥 violating the Supremacy Clause of the U.S. Constitution.
鈥淭he United States has well-established, preeminent, and preemptive authority to regulate immigration matters,鈥 according to the lawsuit, which was filed in federal court in Denver.

ICE enforces U.S. immigration laws nationwide but seeks state and local help, particularly for large-scale deportations, and requests that police and sheriffs alert ICE to people it wants to deport and hold them until federal officers take custody.
The Department of Justice has filed similar lawsuits against Chicago and Rochester, New York.
Justice Department attorneys argue Colorado’s 鈥渟anctuary policies鈥 allowed the to seize control of an apartment complex in the Denver suburb of Aurora.
Local officials have called Trump鈥檚 claims that the gang had taken over large swaths of the city exaggerated, but acknowledged the apartment complex was terrorized, including by people linked to Tren de Aragua.
Friday鈥檚 lawsuit lists as defendants Democratic Gov. Jared Polis, the state Legislature, Denver Mayor Mike Johnston and Colorado Attorney General Phil Weiser.
Polis spokesperson Conor Cahill said in an email that Colorado is not a sanctuary state and regularly works with local, state and federal law enforcement agencies.

鈥淚f the courts say that any Colorado law is not valid then we will follow the ruling,鈥 he said. 鈥淲e are not going to comment on the merits of the lawsuit.鈥
Republicans in Congress have to cooperate with the Trump administration鈥檚 immigration agenda. Lawmakers summoned the mayors of Denver, Boston, New York and Chicago to testify last month before the House Committee on Oversight and Government Reform.
The mayors pushed back, defending their communities , not lawless danger zones, and called on Congress to pass immigration reform.
