House Republicans unveiled the American Health  Care Act, already being called Trumpcare, early last week amid a firestorm of criticism. The legislation would freeze Medicaid expansion, eliminate the individual mandate and replace low-income subsidies with limited tax credits, according to the bill. Opponents also contend millions would lose their insurance under Trumpcare.

But Price, a former doctor and Republican congressman from Georgia, told NBC the plan would not adversely affect anyone.

"They'll have choices that they can select the kind of coverage that they want for themselves and for their family, not the government forces them to buy."

"There's cost that needs to come down, and we believe we're going to be able to do that through this system," the longtime opponent of Obamacare added.

"There's coverage that's going to go up," he said.
