"James and a coalition of 20 additional attorneys general from around the nation today filed a multistate lawsuit challenging the Trump Administration’s efforts to allow 3D-printed gun files to be released on the internet", the statement said on Thursday.
Although a federal judge struck down the administration’s previous efforts to ease the rules governing 3D-printed guns, earlier in the day the White House tried to publish new regulations to circumvent the ruling.
In 2015, Defence Distributed, a company that distributes downloadable 3D-printed guns, sued the Obama Administration after the State Department forced the removal of the files from the internet. The company lost cases before multiple federal courts until June of 2018, when the Trump administration settled and allowed distribution.
The company's head, Cody Wilson, said in 2018 that it is "a fundamental human right" to have access to firearms as well as "a fundamental human dignity".
Defence Distributed is a private non-profit open source organisation that had been posting blueprints and plans to assemble guns for free. According to its site, the company's activity is based on the Second Amendment, which provides for US nationals to keep and bear arms.
