Chief Justice John Roberts rejects gun rights activists' bid to block 'bump stocks' gun ban

U.S. Chief Justice John Roberts on Tuesday rejected a bid by gun rights activists to put on hold President Donald Trump’s administration’s ban on “bump stock” gun attachments that enable semi-automatic weapons to be fired rapidly.

Justice Sonia Sotomayor has not yet acted on another similar request.

The ban goes into effect on Tuesday but lower courts have yet to rule on an appeals brought by gun rights activists. An appeals court in Washington already has said that the ban will not go into effect in relation to the specific people and groups involved in that case.
