Healthcare reform is the top priority for the U.S. government this year, and the momentum is there to achieve it, Health and Human Services Secretary Kathleen Sebelius said. Sebelius said there was "unprecedented" bipartisan cooperation to speed through reforms this year. "In the Senate, Democrats have been working closely together and with their Republican counterparts. Key chairmen have committed to passing reform legislation out of their respective committees in June," Sebelius said.
