A controversial new bill that would impose multiple restrictions on carrying concealed firearms in New Jersey could be law by the end of the week.

The state Senate gave final approval to the bill on Monday. All of New Jersey’s Republican state senators voted against the bill, along with Democratic state Sen. Nick Sacco.

Democrats say the measure is necessary after the U.S. Supreme Court struck down New York's restrictions on concealed weapons. But Republicans say the New Jersey law is unsafe and unconstitutional.

“I think we have a lot of problems in the state of New Jersey, that are much more to do with illegal guns, rather than lawful gun owners. And I think that's where we should focus much more of our scrutiny rather than the legal gun owner, who now wants to protect themself,” says Republican state Sen. Mike Testa.

The bill mandates insurance and training for concealed gun carriers. It also creates numerous gun-free zones throughout the state. Gov. Phil Murphy is expected to sign the bill into law.
