WASHINGTON – Spurred by a horrific elementary school shooting, President Barack Obama vowed to send Congress new policy proposals for reducing gun violence by January.

"This time, the words need to lead to action," Obama said Wednesday. He tasked Vice President Joe Biden with leading an administration-wide effort to create the new recommendations and pledged to push for their implementation without delay.

The president, who exerted little political capital on gun control despite a series of mass shootings in his first term, bristled at suggestions that he had been silent on the issue during his first four years in office. But he acknowledged that Friday's deadly shooting had been "a wake-up call for all of us."
