The Supreme Court won't stop the Trump administration from enforcing its ban on bump stock devices, which allow semi-automatic weapons to fire like machine guns.
The ban took effect Tuesday. Gun rights groups asked the court on Monday to stop the government from enforcing the ban for now. Chief Justice John Roberts declined one request for the court to get involved on Tuesday and a second request was declined by the court on Thursday. That was the only remaining request.
The administration's ban puts it in the unusual position of arguing against gun rights groups.
President Donald Trump said last year that the government would move to ban bump stocks. The action followed a 2017 Las Vegas shooting where bump stocks were used. Fifty-eight people were killed.
