U.S. Senate Unanimously Passes Defense Spending Bill

The U.S. Senate on Tuesday voted 98-0 to approve a wide-ranging defense bill that authorizes $631.4 billion in funding for the U.S. military, the war in Afghanistan and nuclear weapons.

The bill, passed after five days of debate and consideration of hundreds of amendments, must be reconciled with the version passed by the House of Representatives before it can go to President Barack Obama to be signed into law.

There are several key differences between the House and Senate bills, including whether to back continued work by the military on developing biofuels for jets and warships.

Senate Armed Services Committee Chairman Carl Levin said the key challenge facing the bill's enactment was the short amount of time available for House and Senate negotiators to come up with a compromise version. He said staff discussions had already begun.

The top Republican on the committee, Senator John McCain, said he was confident that the House and Senate would be able to resolve the differences between the two bills.

Both senators said they were pleased that they had been able to shepherd the bill to Senate passage under an open process that allowed debate on amendments without having to deal with any threatened procedural roadblocks known as filibusters.

Senate Majority Leader Harry Reid, a Democrat, has promised to try to change Senate rules when the new congress convenes next month to curb filibusters, which have become commonplace.

The Senate bill includes a new round of Iran sanctions, a permanent ban on transferring detainees from Guantanamo to the United States, and prohibitions on the military detention of U.S. citizens.

A measure included in the bill would require U.S. defense contractors that work on classified programs to notify the government if their computer networks are breached.

The bill also bans funding for a missile defense project funded jointly by the United States, Germany and Italy - the Medium Extended Air Defense System (MEADS) that is built by Lockheed Martin Corp and its partners in Italy and Germany.

Defense Secretary Leon Panetta had urged lawmakers to include $400.9 million as final funding for the program, which is being discontinued after this year.

The White House threatened to veto the bill over the changes to the Pentagon's proposed budget and the restrictions on transfers of Guantanamo detainees.

The bill includes a provision that would lift the ban on women in the military using their health insurance for abortion care in cases of rape or incest, and another that would require creation of a comprehensive suicide prevention program.

It also includes an overhaul of wartime contracting rules after the Commission on Wartime Contracting in Iraq and Afghanistan found the United States had squandered up to $60 billion through waste and fraud on contracts in those countries.
