US President Obama has said that he wants "concrete proposals" to curb gun violence by the end of next month, in the aftermath of the Newtown school massacre in Connecticut.
He has asked vice-president Joe Biden to coordinate the campaign and said that he will push legislation "without delay".
52% of Americans favour major restrictions on guns or making all guns illegal, according to a new CNN/ORC poll.
