US President Barack Obama is launching an administration-wide effort to curb gun violence, underscoring the growing political consensus over tightening gun restrictions following the horrific massacre at a Connecticut elementary school.

Obama is tasking vice president Joe Biden, a longtime gun-control advocate, with spearheading the effort. In remarks from the White House on Wednesday, Obama will outline a process for pursuing policy changes following the school shooting, though he is not expected to call for specific measures.

The president has vowed to use “whatever power this office holds” to safeguard the nation’s children after Friday’s shooting at Sandy Hook Elementary.

Many pro-gun lawmakers also have called for a greater focus on mental health issues and the impact of violent entertainment. Obama also prefers a holistic approach, with aides saying stricter gun laws alone are not the answer.
