President Trump plans to seek what he’s calling a “historic” $54 billion increase in defense spending, while pursuing cuts elsewhere in the federal government, as part of his upcoming budget plan.

White House budget officials announced the proposed military spending boost Monday morning, saying the president will seek a commensurate reduction in spending across other federal agencies. Minutes later, Trump previewed the move while addressing the nation’s governors at the White House.

“This budget will be a public safety and national security budget,” Trump said. He said the plan would include a “historic increase in defense spending to rebuild the depleted military.”
