The Trump administration files a lawsuit against Denver and the city’s police department seeking to overturn an assault weapons ban that has been in place since 1989. Multiple reports say the U.S. Department of Justice (DOJ) is asking a court to repeal the long-standing city regulation that restricts certain assault weapons. One outlet notes the legal action comes after Denver’s mayor publicly rejected the administration’s request to remove the ban. The lawsuit is described as part of a broader effort by the DOJ to challenge and eliminate local restrictions on assault weapons. The reports indicate the administration’s case targets both Denver itself and its police department, which are positioned as key parties in enforcing the ordinance. At the same time, details of the administration’s specific legal arguments and the ban’s exact scope are not included in the excerpts provided. The matter is ongoing, with the outcome depending on how the courts respond to the government’s request to strike down the 1989 policy.
