Vice President Joe Biden plans to convene on Thursday the first meeting of a new White House task force charged by President Barack Obama with drawing up a plan to tackle gun violence in the United States.
After the White House meeting convened by Biden, Attorney General Eric Holder is to travel to Newtown to meet privately with law enforcement officials investigating the massacre.
The National Rifle Association, the powerful firearms lobby which has long resisted any effort to restrict gun ownership, signaled this week it may be ready to bend. It said it would offer "meaningful contributions" to prevent future such massacres at an event in Washington on Friday.

In Newtown, a few dozen residents met at the town library on Wednesday night to discuss ways they could influence the national debate. Senator Richard Blumenthal told the group it was time for a "seismic change" in gun policies.

Speaking at the town library meeting, Connecticut Senator-elect Chris Murphy urged the participants to use the formerly quiet suburb's time in the national spotlight to pressure lawmakers in Washington to act.
"The most important thing is to build a movement here, to build a network," Murphy told the group, Newtown United. Both Murphy and Blumenthal are Democrats.
Democrats in Congress who favor gun control have called for quick votes on measures to ban assault weapons or high-capacity magazines, hoping that the slaying of the 6- and 7-year olds in Newtown might be a tipping point to win over more lawmakers.
The backlash against guns has not been limited to lawmakers. Retailers including Wal-Mart Stores Inc took down an informational website about Bushmaster rifles, the sort used in the attack.
