Federal Government Accuses State and City of Blocking Immigration Enforcement
The U.S. Department of Justice (DOJ) has launched a lawsuit against the state of Colorado and the city of Denver. Federal attorneys claim both jurisdictions have enacted sanctuary laws that obstruct federal immigration enforcement.
Filed Friday in Colorado District Court, the lawsuit targets Governor Jared Polis, the state legislature, Denver Mayor Mike Johnston, and Attorney General Phil Weiser. The DOJ argues that their policies directly violate the Supremacy Clause of the U.S. Constitution.
“The United States has well-established, preeminent, and preemptive authority to regulate immigration matters,” the lawsuit reads.
What Are Sanctuary Laws?
Sanctuary cities are areas where local officials limit cooperation with federal immigration authorities. These policies are meant to protect undocumented immigrants from detention and deportation. Critics argue they create safe havens for criminals. Supporters say they build trust between immigrant communities and law enforcement.
Feds Point to Gang Control in Aurora
One focus of the lawsuit is an apartment complex in Aurora, a Denver suburb. The DOJ claims the Venezuelan gang Tren de Aragua, also known as TdA, gained control of the area, exploiting local policies that prevented cooperation with immigration officials.
The apartment complex, called The Edge at Lowry, has now been condemned. Five housing structures have been shut down. Police and city officials described the scene as dangerous and unmanageable.
Local leaders admit there were problems but say the Trump administration’s claims were exaggerated. They confirmed gang activity, including people connected to TdA, but deny that the gang “seized” control of entire areas.
Not the First Legal Challenge
This lawsuit is not unique. The DOJ has filed similar complaints in cities like Rochester, New York, and Chicago. In each case, the department argues that sanctuary policies directly interfere with federal immigration operations.
U.S. Immigration and Customs Enforcement (ICE) leads those operations. ICE frequently asks local police to notify and detain certain migrants so federal agents can take custody. When cities or states refuse, ICE claims it puts communities at risk.
Governor Polis Responds
Governor Jared Polis’ office said Colorado does not consider itself a sanctuary state. His spokesperson, Conor Cahill, told the Associated Press that Colorado cooperates regularly with law enforcement at all levels.
“If the courts say that any Colorado law is not valid, then we will follow the ruling,” Cahill said. “We are not going to comment on the merits of the lawsuit.”
Political Battle in Washington
The issue is also heating up in Congress. Republican lawmakers continue pressing Democratic-led cities to comply with federal immigration rules. They support President Trump’s call for mass deportations and stronger enforcement.
Last month, GOP members summoned mayors from Denver, Boston, New York City, and Chicago to testify before the House Committee on Oversight and Government Reform. The mayors defended their cities, rejecting claims that sanctuary policies promote lawlessness.
They described their communities as safe and inclusive. They also challenged Congress to pass meaningful immigration reform, calling enforcement without reform incomplete and harmful.
The Road Ahead
The outcome of the lawsuit could have nationwide implications. If the DOJ wins, states and cities may be forced to reverse long-standing policies. If the courts reject the lawsuit, it could strengthen local autonomy in immigration matters.
As the legal fight unfolds, the debate between federal power and local rights will remain in the spotlight.
