trigger that would raise taxes automatically if the growth projections were not met. bob corker was okay with this bill, as long as there was a deficit trigger. that, essentially, got killed tonight. that set off a scramble, because republican leaders are facing the very real potential that bob corker and potentially others, like ron johnson, could bail on this bill at such a late hour. so as of now, the scramble is still on and they are still working out ways to move forward. >> yeah, it's going to be a long night. a long week and a long couple weeks for them. sunlen, what is the way forward here? do we know what is going to happen? >> reporter: it is very, very unclear. people are still working here late on capitol hill. there's still a frenzy of activity up here, where they're trying to look through different proposals. how they can satisfy deficit hawks like bob corker through other proposals. that's all to say they are still writing this bill, essentially, a bill that they potentially could be voting on tomorrow. so certainly, a lot of concern here. will people be able to read specifics of what changes are made in this bill at this very late hour.
