BOTTOM LINE ON THE TOP LINE: President Trump has issued his budget guidance to his agencies, and it comes down to very simple math: Subtract $54 billion from non-defense discretionary domestic spending, add it to the Pentagon’s budget, and voila! You have a 10 percent increase in military spending without adding to the deficit. The top line defense number for the base budget for fiscal 2018 is $603 billion. As OMB Director Mick Mulvaney explains it, it’s a blueprint, not a full-blown budget proposal. “So you’re not going to see anything in here that has to do with mandatory spending, entitlement reforms, tax policies, revenue projections or the infrastructure plan.” On Fox, Mulvaney compared it to Americans figuring out their personal finances. “Your family sits down and says ‘OK, here’s what we’re going to spend this year on three or four large line items.’ ”

THE NUMBERS: Discretionary spending for the federal budget is over $1 trillion, $603 billion for defense and $462 billion for non-defense spending. The White House touts the $54 billion plus-up for the Pentagon as “one of the largest increases in history” for defense spending, and “the largest proposed reduction in domestic spending since the early years of the Reagan administration.”
