President Barack Obama has been vague about details of his healthcare reform efforts, but he provided a hint on Monday of one direction he could take -- community health centers. As he announced the nominations of his two top health executives, Obama highlighted the allocation of $155 million to 126 community health centers as part of the $787 billion economic stimulus package. "These health centers will expand access to care by helping people in need -- many with no health insurance -- obtain access to comprehensive primary and preventive health care services," Obama told a news conference.
