"The House passed its version of the FY2007 defense authorization bill, H.R. 5122, on May 11. The bill authorizes $513 billion for national defense, including $50 billion in emergency funding for operations in Iraq and elsewhere in the first months of the fiscal year. The Senate Armed Services Committee marked up its version of the bill, S. 2766, on May 4. It also authorizes $513 billion, including emergency funding. Senate floor action appears likely in June. House subcommittee markup of the defense appropriations bill is tentatively scheduled for June 7. The White House released its FY2007 budget request on February 6, 2006. The request included $513.0 billion in new budget authority for national defense, of which $50 billion was a placeholder for a later budget amendment for costs of overseas operations, $441.2 billion was for regular programs of the Department of Defense (DOD), $17.0 billion was for Department of Energy (DOE) nuclear weapons programs, and $4.8 billion was for defense activities of other agencies."
