President Obama's budget carves out $879 billion for health and human services spending, a 7.7% increase that includes more money for items such as cancer research and food-safety inspectors. The budget includes about $600 billion over a decade that would help pay for the president's healthcare overhaul. That's expected to account for roughly half of the total cost of the expansion. Congress is now sketching out the details on exactly how the overhaul will be financed and what measures it will include.
