Responding to the school shooting massacre in Newtown, Connecticut, President Obama unveiled a sweeping package of gun safety proposals Wednesday.  In a White House event, Obama said Congress must act.  He urged lawmakers to pass legislation requiring "universal background checks" for gun purchases.  He also called for a ban on military-style assault weapons and limits on ammunition clips.  

Obama also signed 23 executive actions aimed at curbing gun violence.  Some involve mental health and school safety initiatives, along with information-sharing on background checks. The President also called on parents, law enforcement officers and community leaders to pressure Congress to approve his legislative proposals.  Any new gun controls will face stiff opposition in the Republican-led House and from the powerful firearms industry.  Centrist Democrats from conservative districts and states are also reluctant to embrace new gun regulations.
