Judge pushes pause on Trump admin’s plans for 3D-printed guns. A federal judge in Washington State issued a temporary injunction blocking a Trump administration rule change that would allow the sharing of 3D-printed gun schematics online. Twenty-one states are suing over the proposed change, which would transfer regulatory authority of 3D-printed guns from the State Department to the Commerce Department. They argue the switch will make it much easier to publish and share plans for the homemade, untraceable weapons on the Internet. The judge agreed: “The proliferation of 3D gun files on the internet likely renders ineffective arms embargoes, export controls and other measures used to restrict the availability of uniquely dangerous weapons sought by those seeking to commit acts of terrorism or other serious crimes.”

Rhode Island lawmakers brace for gun-rights protest amid coronavirus outbreak. The House Judiciary Committee will hold hearings Wednesday on 18 gun-related bills, including a ban on high-capacity magazines. Hundreds of people are expected to attend — the National Rifle Association asked its members in the state “to make their presence known” at the State House. Senate President Dominick Ruggerio invited the public to submit email testimony instead. “You will see me with a lot of Lysol wipes & Purell,” said Representative Justine Caldwell.
