the challenge now is whether senate majority leader mitch mcconnell will bring anything to the floor for a vote. >> keep why your eyes on the prize here. keep your eyes on the background checks. last time after the shooting in connecticut, we didn't do that. and the public got confused about what we were trying to do on the floor. it was four or five different pieces of legislation. if they fail to pass it, the american people will know that something that 90% of the american people support, mitch mcconnell and the republicans refuse to move forward. >> a challenge in the sense that the house democrats want more. mitch mcconnell probably wants nothing. a, can mcconnell get there? b, can the democrats say fine, we'll take one item as opposed to the four or five or six that we would like? >> reporter: there's a couple of hypotheticals down the road
