McCain, chairman of the Senate Armed Services Committee, revealed details Thursday evening of a planned amendment he’s previously teased for the National Defense Authorization Act (NDAA) during a speech at the Brookings Institution.

“When the legislation comes to the floor next week, I will offer an amendment to increase defense spending above the current spending caps, reverse short-sighted cuts to modernization, restore military readiness and give our service members the support they need and deserve,” said McCain, who later added that he may seek $18 billion, not $17 billion. “I do not know whether or not this amendment will succeed, but the Senate must have this debate, and senators must choose a side.”
