WASHINGTON (AP) — The Supreme Court says it won't take up two cases that involved challenges to a ban enacted during the Trump administration on bump stocks, the gun attachments that allow semi-automatic weapons to fire rapidly like machine guns.

The justices' decision not to hear the cases comes on the heels of a decision in June in which the justices by a 6-3 vote expanded gun rights, weakening states' ability to limit the carrying of guns in public.

The cases the justices declined to hear were an appeal from a Utah gun rights advocate and another brought by the gun rights group Gun Owners of America and others.

As is typical the justices made no comments in declining to hear the cases and they were among many the court rejected Monday, the first day of the court's new term.
