King supports the Patient Protection and Affordable Care Act (ACA or Obamacare), but has expressed support for modest adjustments to the legislation if they can be done on a bipartisan basis. In 2013 he voted to restore funding for the ACA as part of an amendment to legislation that funded government operations for 45 days. He has said that those opposed to the ACA who are attempting to discourage people from purchasing health insurance are "guilty of murder" and that doing so was "one of the grossest violations of our humanity that I could think of." In making this comment, King noted a time in his life when he believed he would have died had he not just acquired health insurance.
