In the wake of Dianne Feinstein's assault weapons ban, and Barack Obama's 23 executive orders on gun control, there are other gun measures that Congress is moving forward with.

One notable piece of legislation: Sen. Joe Manchin (D-W.Va.) said Thursday that he was working on a bill with Senate colleagues and the National Rifle Association (NRA) that would implement universal background checks, a major component of President Obama's proposed gun-control reforms.

Manchin, a member of the NRA, had not previously endorsed any specific measures to address gun violence, specifically Feinstein's bill. 

"I’m working on a bill right now with other senators — Democrats and Republicans — we’re trying to get it, and looking at a background check that basically says that if you’re going to be a gun owner, you should be able to pass a background check, to be able to get [universal background checks]," Manchin told Metro News radio's "Talkline," in an interview reported by The Washington Post.
