WASHINGTON (Reuters) - The U.S. Senate voted on Tuesday to limit debate on a $612 billion defence authorization bill, clearing the way for a vote on passage, although the measure's future is clouded by a dispute between Republicans and Democrats over government spending policy.
The White House has said President Barack Obama would veto the bill if it is passed in Congress because of the "irresponsible" way it boosts military spending.
The House of Representatives passed the National Defence Authorization Act last week.
