pass the bill by christmas have brushed off those attacks, saying a future congress would never allow those increases to actually occur and focussing instead on what sources in both chambers say has been the driving force behind the whole process thus far. i have high confidence the senate is going to pass this bill. i know the house is going to pass this bill. i m one of those people who believes failure is not an option. before the end of the yearier. yeah, before the end of the year. reporter: and, jake, that political imperative has really been the driving force. there is no shortage of potential thorny issues. the house is on the precipice of passing this. look over to the senate, whether it s ron johnson, susan collins, perhaps lisa muir cuss ki, jeff flake on deficit issues. the big question now is does the political imperative or the right now gop leaders think it will be the former. all right. phil mattingly on capitol hill for us. thanks so much. lots of breaking
