As Congress continues to haggle over the repeal and replacement of Obamacare, South Carolina Gov. Henry McMaster on Tuesday sent a letter to Sen. Majority Leader Mitch McConnell urging that the law be repealed.

“The voters elected President Trump and Republican majorities in Congress on promises that they would implement a cost-effective, free market replacement for Obamacare,” he wrote.

“The cost increases resulting from this top-down, one-size-fits-all approach have resulted in higher insurance premiums and rising health care costs," he added. "We must fix this problem before it’s too late.”

While Obamacare, or the Affordable Care Act, was initially unpopular with voters, today 51 percent of people in the latest Kaiser Family Foundation Health Tracking Poll have a favorable view of it while 41 percent don’t.

South Carolina Gov. Henry McMaster has written Senate Majority Leader Mitch McConnell to tell him what the Republican effort to repeal and replace the Obama health care law should contain.

McMaster on Tuesday wrote the Kentucky Republican to consider a replacement measure that provides a "free market accommodation" for people with pre-existing conditions.

McMaster was one of the state attorneys general that sued the Obama administration over its health care law. The Republican also said he favors "reasonable caps on Medicaid spending."

McConnell says he plans to unveil a revised health care bill Thursday with a vote on moving ahead on the measure next week. Republicans remain largely divided on the legislation.
