Here's what doctors and patients think about the Republican healthcare bill

The Obamacare replacement plan is headed for a vote in the House on Thursday afternoon.

That's after some changes have been made to the American Health Care Act, the bill that aims to repeal and replace the Affordable Care Act.

The bill now includes a new addition, called the MacArthur amendment. The amendment would allow states to receive waivers to avoid some of the regulations set up under the ACA. And on Wednesday, Rep. Fred Upton introduced an amendment that allowed for $8 billion in funding to protect people who are sick in the case that those waivers are triggered.

The two amendments have led to dozens of patient advocacy groups and physician groups to speak out.
