Is the military "gut checking" the politicians on the budget?

So Sen. Johnny Isakson (R) is fricken OUTRAGED that the cuts are happening at Ft. Benning. He is "Demanding Answers"!

Sen. Dan Sullivan (R) said he was “extremely frustrated” with 2,700 slots being cut in Alaska!

So who sets the budget and what party is in power anyway?
