A debate over the military’s budget is emerging between defense hawks on Capitol Hill and fiscal hawks in the Trump administration. The fiscal hawks, chief among them Office of Management and Budget director Mick Mulvaney, want the next annual defense budget set at $603 billion, a 3 percent increase from the last Obama budget request. The defense hawks say that after years of budget caps and cuts known as sequestration, a 3 percent hike won’t accomplish President Trump’s directive to “rebuild” the military.
