President Obama will formally name Vice President Biden on Wednesday as the head of the administration's working group assigned to come up with ways to reduce gun violence following the Newtown, Conn., shootings.

The White House said Obama will make the announcement late Wednesday morning. Biden, a gun-control advocate during his years in the Senate, will supervise what the administration described as an "inter-agency" process to draw up a comprehensive strategy to address gun violence and the mass shootings that have battered a handful of communities during Obama's tenure.
