'Package of concrete proposals' on guns coming Wednesday from WH Updated 1:05 pm -- President Barack Obama will publicly announce his gun-safety proposals on Wednesday, with the new recommendations including some executive actions in addition to legislative proposals like a ban on assault weapons and large capacity magazines. "Tomorrow, the president and the vice president will hold an event here at the White House to unveil a package of concrete proposals to reduce gun violence and prevent future tragedies like the one in Newtown, Connecticut," White House spokesman Jay Carney said during a briefing Tuesday afternoon. President Obama and Vice President Biden will announce a package of gun control proposals in response to the Connecticut school massacre, says White House spokesman Jay Carney. Carney said that the president will be joined at the 11:45 a.m. event by children from around the country who wrote the White House with concerns about gun violence in the wake of the Newtown school shootings that left 20 children dead. He added that the president has previously backed a "comprehensive approach" including an assault weapons ban and a measure to ban high-capacity clips, but he stressed that both items will require congressional action. "The president will take a comprehensive approach, but it is a simple fact that there are limits on what can be done within existing law and Congress has to act on the kinds of measures that we've already mentioned, because the power to do that is reserved by Congress," Carney said of the need for "significant" action on gun control measures.
