House Ways and Means Committee Chairman Kevin Brady told CNBC on Thursday there's 95 percent agreement on the GOP's health-care bill.
"But in Washington, that last 5 percent really matters, especially if you're ripping up a huge entitlement [and] making huge replacement decisions," the veteran Texas congressman said on "Squawk Alley," ahead of the scheduled evening House vote on the Republican plan to repeal and replace Obamacare.
President Donald Trump was meeting Thursday with the House Freedom Caucus to try to get the conservative group to drop its opposition. GOP leaders offered a tweak of their plan Wednesday night to include getting rid of the set of minimum benefits required of insurers.
Brady refused to comment on the outcome of negotiations, but said: "At the end of the day, let's do all that we can eliminate the federal mandates, let those new innovative affordable plans take life back in the states."
The House vote is seen as a major test for Trump's agenda because he's said the Obamacare replacement needs to happen before other priorities such as tax cuts for individuals and corporations.
As the nation's top tax writer, Brady was anxious to get the GOP health plan out of the House and into the Senate.
"My love is tax reform," he said. "So passing this eliminates nearly a trillion dollars in taxes. That makes our tax reform even more pro-growth and more bold."
