This nebulous statement was being pushed for by Republican Sen. Jeff Flake, Lindsey Graham and other Republican "moderates" in exchange for a new continuing resolution reopening the federal government until the same date.
Sen. Jeff Flake (R-Ariz.) also believed a solution was within reach to debate an immigration bill in the chamber by Feb. 8, even if a broader deal were not reached by then.
The best-case scenario, Flake added, “is to pass the bill with a good Senate majority, have a process up here, and have the president support it if we can get 60 or 70 votes. I believe he will and if he does, that’ll move the House.”
Flake was already played by McConnell in a December promise by the Majority Leader to bring DACA up for a vote that McConnell, has since that time, ignored; this new assurance may prove enough for Flake (again) and would-be Trump negotiator Graham, but it's not clear such a weak non-promise will sway the votes of enough Democrats for the resolution to pass.
Democrats have little patience for McConnell after a long series of broken assurances; McConnell's own announcement of the potential deal, couched in repeated insults of his Democratic counterparts, is not likely to gain him any favors. With Flake and Graham, McConnell needs only seven more Democrats to "trust" him on his latest not-yet-broken assurance.
Under this plan, a vote for a new three-week continuing resolution that includes six years of new CHIP funding will be held tomorrow at 12 ET. If it passes, attention turns to Paul Ryan and House Republicans to both agree to those terms and to either publicly support or block further DACA negotiations in those next three weeks. McConnell can make no promises that the House will take any DACA action at all, meaning the threat of mass deportations for child immigrants remains.
