(CNN) -- President Barack Obama said Wednesday that the National Rifle Association, which leads the pro-gun lobby in the United States, "has members who are mothers and fathers" likely impacted by the Connecticut school shooting that killed 20 young children. The nation will have a set of recommendations to address widespread gun violence within weeks, President Obama announced Wednesday. Vice President Joe Obama will lead an inter-agency group to come up with "concrete proposals no later than January -- proposals that I then intend to push without delay," the president said.
