(MCT) — Illinois' leading Democrats on Monday pushed for more gun control in the wake of last week's school shootings in Connecticut, but gun-owner rights groups criticized the move as politicizing a national tragedy and said they were prepared to fight in Washington and Springfield.

U.S. Sen Dick Durbin, the state's senior senator and the No. 2 Democrat in the chamber, called for congressional hearings aimed at finding constitutional limits to Second Amendment rights while Gov. Pat Quinn and Mayor Rahm Emanuel re-emphasized their long-standing call to ban semi-automatic, assault-style weapons at the state and federal level.
