The Trump administration filed a lawsuit against Denver and its police department on Tuesday, challenging the city’s 35-year-old ban on assault weapons. The legal action seeks to overturn an ordinance that has prohibited the possession of assault weapons in Colorado’s capital since 1989.

The federal lawsuit comes just one day after Denver officials publicly and emphatically refused Department of Justice demands to repeal the ban. The administration claims the ordinance violates Second Amendment protections under the U.S. Constitution.

“The Constitution is not a suggestion and the Second Amendment is not a second-class right,” acting Attorney General Todd Blanche said in a statement. “Denver’s ban on commonly owned semi-automatic rifles directly violates the right to bear arms.”

Federal attorneys had previously contacted city officials last week, requesting they cease enforcement of the ban and enter negotiations to resolve the dispute without litigation. Denver’s response was unambiguous.

“Our answer is hell no,” Mayor Mike Johnston declared during a Monday news conference. “No, we will not roll back a common sense policy that has kept weapons of war off of these city streets for 37 years. No, we will not put first responders at greater risk every time they respond to a dangerous incident.”

The lawsuit represents a significant escalation in the ongoing national debate over gun control measures. The Trump administration is simultaneously threatening similar legal action against the state of Colorado over its statewide ban on large-capacity ammunition magazines, enacted following the 2012 Aurora movie theater mass shooting that left 12 dead and 70 injured.

Denver Police Chief Ron Thomas defended the city’s ordinance, noting that he joined the department the same year the ban was implemented. He credited the measure with helping address gun violence, pointing out that of 2,100 firearms recovered in Denver last year, fewer than 2% were assault-style weapons.

In their federal complaint, Justice Department attorneys argue that Denver’s ban encompasses AR-15-style rifles owned by at least 16 million Americans. The government characterizes these as “ordinary semiautomatic rifles” used for lawful purposes, “including but not limited to self-defense.”

Colorado has experienced multiple devastating mass shootings over the past two decades. These include the 1999 Columbine High School massacre that killed 14 people, the 2021 Boulder supermarket shooting that claimed 10 lives, and a 2022 attack at an LGBTQ nightclub in Colorado Springs where five people died.

The legal battle extends beyond Denver’s ordinance. The Trump administration recently demanded Colorado stop enforcing its statewide ban on large-capacity magazines, which the Colorado Supreme Court upheld in 2020. In an April 28 letter to state officials, Assistant Attorney General Harmeet Dhillon threatened litigation unless the state agrees the law is unconstitutional.

“Law-abiding Americans own literally hundreds of millions of magazines identical to those banned in Colorado,” Dhillon wrote.

Colorado Attorney General Phil Weiser defended the magazine capacity restrictions, arguing that firearms with large-capacity magazines pose a significant public safety threat. “Large-capacity magazine laws are responsible policies that decrease the deadly impacts of mass shootings and save lives,” Weiser said in a statement.

The lawsuit reflects the broader tension between local gun control efforts and federal interpretations of Second Amendment rights. It comes at a time when gun violence continues to be a polarizing political issue nationwide, with significant implications for public safety policy across jurisdictions.

The Denver case could potentially set precedent for similar ordinances in other municipalities across the country, as courts continue to define the scope of Second Amendment protections following recent Supreme Court decisions that have expanded gun rights.
