TRENTON - Parents of four of the children killed in Newtown, Conn. joined state lawmakers for a press conference in Trenton Tuesday as several gun control bills are being considered in the State House.

The families came in support of legislation that would ban high-capacity magazines. The bills currently in consideration would expand background checks to include mental health records, add a photo to the purchaser's ID card, and ban certain types of rifles.

“The issue of gun violence transcends state lines and politics,” said Nicole Hockley, mother of a Newtown victim.

Majority Leader Lou Greenwald believes the legislation is necessary to prevent tragedies similar to the Newtown shooting.

"If this tragedy had been transplanted from Connecticut to New Jersey, the reality is we'd be passing this legislation now," said Greenwald.

Gun rights advocates were also there to argue against stricter laws, citing the Second Amendment.
