New Jersey Attorney General Gurbir Grewal is continuing his push to curb gun violence across the country.

Grewal announced Tuesday that New Jersey is leading a coalition of 12 states to defend a law in Hawaii that would prevent people from carrying a firearm in public unless they can demonstrate a need to do so.

A panel of judges ruled in June that Hawaii cannot set those guidelines, citing the Second Amendment.

Grewal said in a statement, “...the evidence is clear that when more people carry guns in public, public confrontations get more dangerous, not only for the public, but also for our law enforcement officers."

Grewal and Gov. Phil Murphy have made gun reform a large part of their time in office.

Earlier this year, the state sued Texas-based Defense Distributed founder Cody Wilson to prevent blueprints from 3D-printed guns from being published in the state.

Cease-and-desist letters were sent to so-called “ghost gun” manufacturers to warn them that sales of these types of untraceable guns violate state law.

Gov. Murphy installed a practice that issues quarterly reports on gun crimes in New Jersey and also signed a law that limited large-capacity magazines.
