In March 2017, Mulvaney said the Congressional Budget Office was not capable of assessing the American Health Care Act, stating that "[i]f the CBO was right about Obamacare to begin with, there'd be eight million more people on Obamacare today than there actually are." According to FactCheck.Org, "[t]he CBO actually nailed the overall impact of the law on the uninsured pretty closely... It's true (as Trump administration officials have repeatedly pointed out) that CBO greatly overestimated the number who would get government-subsidized coverage through the new insurance exchanges. But at the same time, CBO underestimated the number who would get coverage through expanding Medicaid. And whatever the failings of CBO's predictions, they were closer to the mark than those of the Obama administration and some other prominent forecasters." PolitiFact noted that "the initial CBO analysis of the Affordable Care Act did forecast that more people would participate in health care exchanges than actually did, but the CBO has revised those estimates. Moreover, independent analyses, as well as experts agree that the CBO offers some of the best estimates given the information available at the time."
