WASHINGTON -- The White House confirmed Tuesday that President Barack Obama will throw his weight behind passing an assault weapons ban, among other items, when he unveils his gun violence package on Wednesday.

"There are specific legislative actions that [Obama] will continue to call on Congress to take, including the assault weapons ban, including a measure to ban high-capacity [gun magazines], including an effort to close the very big loopholes in the background check system in our country," White House press secretary Jay Carney said during his daily briefing.

While it remains to be seen which, if any, of Obama's forthcoming gun violence proposals can pick up the GOP support necessary to pass in Congress, the president's commitment to pushing an assault weapons ban signals that he is prepared to take on even members of his own party, namely Senate Majority Leader Harry Reid (D-Nev.), who said earlier this month that he doesn't think an assault weapons ban can pass and signaled he wouldn't bring it up for a vote.

Carney dismissed the idea that Reid's comments mean an assault weapons ban can't move. "The president has made clear that he supports, and has long supported, a renewal of the assault weapons ban," he said. "The legislative strategy will be something that's worked out with legislative leaders."

Still, Carney acknowledged that Obama's push on the issue "doesn't mean it's a sure thing, either. If these things were easy they would have been done already."

Obama will unveil his gun violence proposals on Wednesday morning with Vice President Joe Biden, who has been holding meetings with various stakeholders on on gun violence over the past month. Also joining the president for the White House event: children who have written letters to Obama about gun violence since last month's shootings in Newtown, Conn.

  • Gabrielle Giffords And Trayvon Martin Shootings

    Gun control advocates had high hopes that reform efforts would have increased momentum in the wake of two tragic events that rocked the nation. In January of 2011, Jared Loughner opened fire at an event held by Rep. Gabrielle Giffords (D-Ariz.), killing six and injuring 13, including the congresswoman. Resulting attempts to push gun control legislation <a href="http://www.huffingtonpost.com/2012/04/09/trayvon-martin-shooting-gun-debate_n_1413115.html" target="_hplink">proved fruitless</a>, with neither proposal even succeeding in gaining a single GOP co-sponsor. More than a year after that shooting, Florida teenager Trayvon Martin was <a href="http://www.huffingtonpost.com/news/trayvon-martin" target="_hplink">gunned down</a> by George Zimmerman in an event that some believed would bring increased scrutiny on the nation's Stand Your Ground laws. While there has been increasing discussion over the nature of those statutes, lawmakers were <a href="http://www.huffingtonpost.com/2012/04/09/trayvon-martin-shooting-gun-debate_n_1413115.html" target="_hplink">quick to concede</a> that they had little faith the event would effectively spur gun control legislation, thanks largely to the National Rifle Association's vast lobbying power.

  • Colorado Movie Theater Shooting

    In July of 2012, a heavily armed gunman <a href="http://www.huffingtonpost.com/2012/07/20/aurora-shooting-movie-theater-batman_n_1688547.html" target="_hplink">opened fire on theatergoers</a> attending a midnight premiere of the final film of the latest Batman trilogy, killing 12 and wounding scores more. The suspect, James Eagan Holmes, allegedly carried out the act with a number of handguns, as well as an AR-15 assault rifle with a 100-round drum magazine. Some lawmakers used the incident, which took place in a state with some of the laxest gun control laws, to bring forth legislation designed to place increased regulations on access to such weapons, but many observers, citing previous experience, were <a href="http://www.huffingtonpost.com/2012/07/20/batman-shooting_n_1690547.html" target="_hplink">hesitant to say</a> that they would be able to overcome the power of the National Rifle Association and Washington gun lobby.
