White House Press Secretary Jay Carney announced this afternoon that President Obama will unveil a "concrete package" of gun control proposals including assault weapons bans, high capacity ammunition magazine bans, and closing loopholes on background checks.

Carney said that the president will be joined by Vice President Joe Biden as well as children who wrote to the president after the Newtown shootings.

"They will be joined by children around the country expressing their concerns about gun violence and school safety, along with their parents," Carney confirmed.

President Obama specifically mentioned children during his December speech in response to the shooting.

"Can we say that we’re truly doing enough to give all the children of this country the chance they deserve to live out their lives in happiness and with purpose?" he asked. "I’ve been reflecting on this the last few days, and if we’re honest with ourselves, the answer is no.  We’re not doing enough.  And we will have to change."

The press conference will take place Wednesday at 11:45 a.m.
