ALBANY, N.Y. (AP) - People familiar with the internal negotiations say Gov. Andrew Cuomo and legislative leaders have a tentative deal to enact the nation's first gun control measure following the Newtown, Conn., school shooting. The tentative agreement would further restrict New York's ban on assault-style weapons and limit ammunition clips to seven bullets, rather than the current 10 bullets. Other elements, pushed by Republicans, would refine a mental health law that allows for civil confinement of people determined to be a threat to others. The people spoke on condition of anonymity because the proposal had not been discussed among rank and file legislators. They say the tentative deal struck over the weekend will be debated in closed-door conference today in the Senate and Assembly. If the deal survives as expected, a bill could be presented this week.
