Because of course he did:
The HIT is an Obamacare tax on health insurance premiums designed to help offset the cost of the tax credits for ACA exchange enrollees. Recognizing the negative impact the tax was having across the nation, Congress worked across the aisle in late 2015 to pass a bipartisan one-year moratorium on the tax for 2017, saving the health care system $21.4 billion.
Republicans were expected to tackle the HIT through the repeal of the ACA. The House-approved measure to repeal and replace the failing law and the two main Senate bills all included provisions to end this irresponsible tax. But, unfortunately, congressional lawmakers weren’t able to pass the legislation.
At its core this is a GOP "divide and conquer" tactic. Without the HIT, the funding for subsidies will disappear, immediately followed by the subsidies themselves. And millions of Americans will no longer be able to afford plans offered through the ACA Marketplace. As far as Folwell's grossly inaccurate claim about the ACA being a "failing law," it's actually he and other Republicans who are making it fail. And they will be responsible for the deaths of thousands of North Carolinians in the long run, so before any of you braniacs at SEANC decide to pat him on the back for this, step back and look at the bigger picture.
