Biden also held conference calls with 15 governors and 16 state and local elected officials Wednesday.
Shortly after the shootings in which 26 children and educators were killed at Sandy Hook Elementary last month, President Obama assigned Biden to head a task force and offer suggestions on curbing gun violence.
"Every once in a while there's something that awakens the conscience of the country, and that tragic event did in a way like nothing I've seen in my career," Biden said Wednesday.
