Spending: $488.8 billion

Percentage change from 2002: +6.4 percent

Highlights:

--$27.2 billion for the National Institutes for Health, double what it was five years ago. Nearly half the increase is dedicated to bioterrorism-related research.

--$190 billion over 10 years to add a prescription drug benefit and make other changes to Medicare.

--Spending cuts to programs including drug prevention and subsidized heating bills.

The president again is asking for $190 billion to add drug benefits to Medicare, less than what many experts say is needed. The administration also wants to let states offer prescription drug packages for senior citizens through Medicaid. And it proposes more money to keep private health maintenance organizations, which typically offer drug benefits, from dropping out of Medicare.

On medical research, Bush asks Congress to complete an effort begun under President Clinton to double the budget for the National Institutes of Health over five years.

The budget would give states the option to let welfare families keep up to $100 a month in child support payments. Those payments now go to offset the cost of welfare checks. Families that have never been on welfare would pay $25 annually if they use the government system to collect child support.

Heating and cooling assistance for poor people would be cut by $300 million; the Centers for Disease Control and Prevention would lose $57 million for its program to fight chronic diseases, and $28 million for its worker safety promotion effort.

Bush repeated several requests from last year, including $100 million for a "compassion capital fund" that would help small groups prepare to handle government grants. He's again asking Congress for tax breaks to promote charitable giving. Notably absent from his proposal--opening new government programs to religious groups, which ran into deep opposition in Congress.

The budget's biggest increase is for bioterrorism prevention, $1.2 billion.
