The plaintiffs, which include Damien Guedes and the Firearms Policy Foundation, had petitioned the court after a lower court's decision to uphold Trump's ban on bump stock devices.
Once connected to a rifle rather than their standard inventory, or finish part, bump stocks enabled rounds to be fired in rapid succession, nearly as quickly as an automatic weapon. Some guns can fire over 400 rounds per minute with a bump stock.
Feds take first steps toward regulating bump-fire stocks after Stephen Paddock killed 58 people attending a concert in Las Vegas.
In 2019, with President Donald Trump's two nominees sitting on the high court, several states advanced a slew of abortion restrictions to stake their claims before what seemed like an imminent battle over abortion rights.
The Trump administration's move was an about-face for the federal Bureau of Alcohol, Tobacco, Firearms and Explosives.
The revised regulation was met with resistance from gun rights advocates, including the groups and gun owners who filed suit in Washington, D.C., and whose appeal the court turned away Monday.
The Trump administration is seeking a sweeping ruling that it could potentially use to deport millions of people, even those arrested far from the border and who have been in the country for years, said Lee Gelernt, the American Civil Liberties Union lawyer who is representing the man at the Supreme Court.
