Vice President Joe Biden touted executive actions taken by the Obama administration to reduce mass violence and pushed for Congress to pass additional gun restrictions ahead of the one-year anniversary of the massacre at Sandy Hook Elementary.

In an email to supporters, Biden highlighted nearly two dozen executive actions imposed by President Obama in response to the shooting in Newtown, Conn., last December, where a gunman killed 20 first-graders and six adults.

“Now, it's not enough to take these steps on our own -- we still need Congress to pass comprehensive legislation to reduce gun violence,” Biden said. “We need expanded background checks, and we need to create serious penalties for gun trafficking. There is no question that these kinds of measures would protect our kids and keep our communities safer.”

Obama was dealt an embarrassing legislative defeat earlier this year when lawmakers rebuffed his call for expanded background checks, an assault weapons ban and a prohibition on high-capacity ammo magazines.

The issue has largely remained on the back burner for the White House since the high-profile defeat. And prospects for a successful push on Capitol Hill have only diminished since then.

Biden, however, alluded to another effort by the White House to tackle the controversial issue.

“We've seen too much gun violence as a country. And if there's even one thing we can do to save a life, it is our most sacred duty to try,” he said.

“That's where I stand,” he added. “And you have my word that the president and I are doing everything we can to make sure no parent loses their child to gun violence."
