Citing the recent shootings at a school in Newtown, Conn., the mayors' question why Congress hasn't taken any action on the issue.

They note that 12 more New Jersey mayors have joined the national Mayors Against Illegal Guns coalition in the past month.

Many of the mayors will join former Gov. Jim Florio and the father of a shooting victim at a news conference Monday to push for more action on illegal guns and a ban on military style weapons. They also plan to unveil a national television advertisement featuring gun violence survivors and victims' family members.

The mayors will travel to Washington on Wednesday to lobby lawmakers.
