Health and Human Services Secretary Kathleen Sebelius testifies on Capitol Hill in Washington, Thursday, April 10, 2014, before the Senate Finance Committee to discuss the HHS Department's fiscal 2015 budget. Sebelius said 7.5 million Americans have now signed up for health coverage under President Barack Obama's health care law. That's a 400,000 increase from the 7.1 million that Obama announced last week at the end of the law's open enrollment period. The figure exceeded expectations, a surprise election-year success for the law after a disastrous roll-out. (AP Photo/Susan Walsh), APTOPIX
