Leadership appeared confident on Friday morning that they had the votes to pass their tax plan.
“We have the votes,” McConnell told reporters after a closed-door caucus meeting.
GOP Sens. Corker and Susan Collins (Maine) have not said how they will vote on the tax legislation.
Flake said in addition to getting rid of an $85 billion “budget gimmick,” he had also secured an agreement to work on a legislative fix for the Deferred Action for Childhood Arrivals (DACA) program.
“The second was to obtain a firm commitment from the Senate Leadership and the administration to work with me on a growth-oriented legislative solution to enact fair and permanent protections for DACA recipients,” he said.
The Trump administration announced earlier this year that it would end the DACA program.
A group of Senate Republicans, led by Sen. Chuck Grassley (R-Iowa), made an offer to Sen. Dick Durbin (D-Ill.) that would pair much of Sen. John Cornyn’s (R-Texas) border security bill with an immigration fix that did not include a path to citizenship.
Some House Democrats, and a growing number of Senate progressives, have pledged to oppose any government spending bill without a deal on DACA.
