FILE - In this March 23, 2010, file photo President Barack Obama is applauded after signing the Affordable Care Act into law in the East Room of the White House in Washington. Government cost estimates for expanding Medicaid to millions more low-income people are increasing faster than expected, raising questions about a vital part of President Barack Obama’s health care law. Estimated per-person costs were an eye-catching 49 percent higher than previously calculated, according to a recent report to Congress from nonpartisan experts with the federal Centers for Medicare and Medicaid Services. The new estimate of $6,366 per person for 2015 was nearly $2,100 higher than expected.(AP Photo/Charles Dharapak, File)
