Mandatory Spending: $67.6 billionHighlights: The Pentagon is proposing savings mainly through ending or shrinking certain weapons programs, shaving health care benefits and reducing military construction. It also would slow the pace of military pay raises. Spending would otherwise be largely the same in all major categories as in 2013. The budget proposal calls on Congress to approve a round of domestic military base closings in 2015, which would cost an estimated $2.4 billion in the short run but save an unspecified amount over the long term. Although the U.S. is winding down its role in Afghanistan, the Pentagon faces enormous costs of pulling out its troops. The 2014 budget includes a "placeholder" figure of $88.5 billion for war costs, although that number is expected to be revised down slightly once the White House makes more decisions about the pace of 2014 troop withdrawals. The budget assumes that the U.S. will have 34,000 troops in Afghanistan at the end of the budget year in September, down from the current 63,000. ___ Agency: Education Total Spending: $56.7 billion Percentage Change from 2013: 10.8 percent decrease Discretionary Spending: $71.2 billion Mandatory Spending: $0 Highlights: Obama's proposed education budget calls for expanded programs for young people before they reach kindergarten and offered Congress two options to consider: a $750 million preschool program for 4-year-old students from four-member families earning $47,100 or less; or a more expansive $2 billion option that would provide universal access to pre-school programs, with incentives for states to offer programs for all families. The proposal requires that up to 5 percent of those funds be used to measure student achievement and collect data. The president's preschool plan would be paid for by a higher tax on tobacco, which the administration said would raise $78 billion over a decade by almost doubling the federal tax on cigarettes to $1.95 per pack.
