WASHINGTON (NEWS1130) – President Barack Obama has asked a team led by Vice-President Joe Biden to offer “concrete proposals” to curb gun violence, in the aftermath of the massacre at a Connecticut school.

Obama set a deadline of no later than January for the recommendations — saying “This time, the words need to lead to action.”

The president says he will push legislation “without delay.” He is urging Congress to hold votes on the bill next year.

Obama says the fact that this problem is complex can no longer be an excuse for doing nothing.

The gunman in Friday’s shooting wielded a semi-automatic rifle to kill 20 children and six adults at the school, after killing his mother at home. He then killed himself.

Obama is also pressing Congress to reinstate an assault weapons ban, which expired in 2004.  And he is calling for stricter background checks for people who seek to purchase weapons and limited high-capacity clips.
