GOP Senate health care bill revision teetering on edge of collapse

Two Republican senators have already said they plan to kill the measure.

If just three Republicans oppose the procedural vote scheduled for next week, the GOP's seven-year effort to repeal the Affordable Care Act would come to an end.

"As a conservative, I won't support the new federal spending or entitlements or bailouts," Paul told reporters shortly after the revised draft was released Thursday.

For Collins, who is known as a moderate on health care, the issue comes down to the deep cuts to Medicaid funding proposed in the revised draft.

"My strong inclination and current intention is to vote 'no' on the motion to proceed," Collins said Thursday.

Several Republicans have said they remain undecided.

Some of the revisions in this version of the bill include: maintaining some Obamacare taxes for the wealthy, allowing people to pay for insurance with pre-tax money and providing financial support to help low-income people purchase healthcare.

In an effort to address some concerns voiced by moderates, the revised bill also includes a $45 billion dollar sweetener to fight the opioid epidemic.

If the procedural vote is successful, an amendment process will begin, meaning the bill will be a work-in-progress until the final vote.
