The Supreme Court is rejecting a challenge to federal regulation of gun silencers, just days after a gunman used one in a shooting rampage that killed 12 people in Virginia.

The justices did not comment Monday in turning away appeals from two Kansas men who were convicted of violating federal law regulating silencers. The men argued that the constitutional right “to keep and bear arms” includes silencers.

Kansas and seven other states joined in a court filing urging the justices to hear the appeal. The states said the court should affirm that the Second Amendment protects “silencers and other firearms accessories.”

President Donald Trump’s administration asked the court to stay out of the case and leave the convictions in place.

Shane Cox, owner of a military surplus store, was convicted of making and transferring an unregistered silencer, and customer Jeremy Kettler was convicted of possessing one, all in violation of the 85-year-old National Firearms Act. Both men were sentenced to probation.
