The Department of Justice filed a lawsuit Friday targeting Colorado and Denver over their immigration-related laws and policies. Officials argue that both the state and city have unlawfully blocked federal efforts to enforce national immigration laws.
This legal move marks the latest escalation in the ongoing federal immigration enforcement conflict. According to the lawsuit, Colorado and Denver passed “sanctuary” measures that violate the U.S. Constitution’s Supremacy Clause.
The lawsuit was filed in federal court in Denver. It claims the federal government holds exclusive authority over immigration matters across the United States.
Officials said that local laws interfere with Immigration and Customs Enforcement (ICE) operations. ICE frequently relies on police departments and local jails to help identify and detain undocumented immigrants.
However, under these “sanctuary” policies, many local agencies decline to share information with ICE. Some local authorities even refuse to hold detainees once their local charges are resolved.
Supporters of these local laws argue they promote trust between immigrant communities and law enforcement. Yet, federal officials maintain that cooperation is essential for national security.
The Justice Department has filed similar lawsuits in other cities. Chicago and Rochester, New York, also face legal action for policies that restrict collaboration with ICE.
Attorney General John Whitaker addressed reporters shortly after the lawsuit was filed in Denver federal court. He stressed the importance of cooperation between federal and local governments.
“The Constitution gives us clear authority over immigration,” Whitaker said. “States cannot obstruct those responsibilities.”
Critics of the lawsuit, however, say it undermines local control and community safety. They argue that heavy-handed enforcement drives fear among families.
Still, the federal immigration enforcement conflict continues to dominate headlines. As the high-profile legal case develops, growing tensions between state and federal officials could shape future legal battles.
Meanwhile, immigrant advocacy groups plan to organize community support across Colorado and Denver. They warn that federal lawsuits could lead to increased deportations and divided families.
For now, both sides are preparing for a long court battle. The federal immigration enforcement conflict shows no signs of ending anytime soon.
