"In the week before Congress adjourned for recess on September 30, the House and Senate passed conference agreements on both the FY2007 national defense authorization bill, H.R. 5122, and the FY2007 defense appropriations bill, H.R. 5631. The President signed the appropriations bill into law, P.L. 109-289, on September 29, and he signed the authorization bill into law, P.L. 109-364, on October 17. The conference agreement on the appropriations bill provides $436.6 billion for defense, including $366.6 billion in regular appropriations and $70 billion in additional appropriations, mainly as a 'bridge fund' for operations abroad. The total of regular appropriations is $4 billion below the Administration request. The Senate passed bill provided $9 billion less than the request, which freed that much to add to non-defense appropriations bills. The White House , however, threatened to veto the defense bill if reduced defense by more than $4 billion."
