President Barack Obama proposed a new assault weapons ban and mandatory background checks for all gun buyers on Wednesday as he tried to channel national outrage over the Newtown school massacre into the biggest U.S. gun-control push in decades.

Rolling out a wide-ranging plan for executive and legislative action to curb gun violence, Obama set up a fierce clash with the powerful U.S. gun lobby and its supporters in Congress, who will resist what they see as an encroachment on constitutionally protected gun rights.

Obama presented his agenda at a White House event in front of an audience that included relatives of some of the 20 first-graders who were killed along with six adults by a gunman on December 14 at Sandy Hook Elementary School in Newtown, Connecticut.

“We can’t put this off any longer,” Obama said, vowing to use “whatever weight this office holds” to make his proposals reality. “Congress must act soon.”
