Rep. Victoria Spartz, R-Ind., announced over the weekend that she is against the current text, while several other fiscal hawks suggested their support is still up in the air.
Two other conservatives, Reps. Tim Burchett, R-Tenn., and Thomas Massie, R-Ky., signaled they would oppose the resolution as well.
Some Republicans are worried about potentially damaging cuts to Medicaid and other federal benefit programs that their constituents rely on. Johnson met with some of those potential holdouts on Monday night for what he called a "very productive conversation."
The speaker sounded optimistic when leaving the Capitol late on Monday, telling reporters, "We’re on track. We got the resolution through rules, and we're expecting to vote tomorrow evening."
The bill aims to increase spending on border security, the judiciary and defense by roughly $300 billion, while seeking at least $1.5 trillion to $2 trillion in spending cuts elsewhere.
As written, the bill also provides $4.5 trillion to extend President Donald Trump's 2017 Tax Cuts and Jobs Act provisions, which expire at the end of this year.
An amendment negotiated by House Budget Committee Chairman Jodey Arrington, R-Texas, and conservatives on his panel would also force lawmakers to make $2 trillion in cuts, or else risk the $4.5 trillion for Trump's tax cuts getting reduced by the difference.

The House Rules Committee is the final gatekeeper for most pieces of legislation before a chamber-wide vote.
The committee will normally debate a set of bills, not necessarily related ones, before setting terms for amendments and debate and advancing those terms out of committee as a single "rules package."

House lawmakers will then vote on the rules package before the final reconciliation framework.
Once this bill passes the House, the relevant committees will get to work filling the framework out with detailed policy priorities, which will then be returned as a final bill that will need to face House passage again.
Johnson said at the Americans for Prosperity event on Monday that he wants that to happen sometime in April.
