The White House said on Monday it so far had “no specific agenda” to announce on tackling gun violence, hours after President Barack Obama warned America must do more to end firearms tragedies. White House spokesman Jay Carney said that Obama would engage Americans “in the coming weeks” on possible approaches, after he pledged at a vigil for last week’s school shooting to use all the powers at his disposal. “I don’t have a series of proposals to present to you. The president spoke yesterday about moving forward in the coming weeks,” Carney said. “I don’t have a specific agenda to announce to you today. I will simply point you to what the president said last night about moving forward in the coming weeks. I would look for him to do that.” Carney did however say that Obama still supported a reinstatement of the ban on assault weapons ban that expired in 2004, following growing talk in Congress about a bid to renew the measure.
