Rubio's push for higher defense spending falls short

Senators blocked an amendment Thursday that would have increased defense spending above congressionally mandated budget caps. 

Senators voted 32-68 on overriding a "point of order" placed on the amendment by Sen.

The amendment would have swapped out the fiscal 2016 defense budget numbers with projected numbers included in former Defense Secretary Robert Gates's fiscal 2012 defense budget. 
"This is a pretty simple amendment, it funds defense fully," Rubio said ahead of the vote. "It puts us at the Gates budget number ... that fully funds the needs of our military." 
Sanders slammed the Republicans' amendment, calling it "remarkable." 
"This is truly a remarkable amendment because it runs directly in opposition to what the Republicans have been talking about," Sanders said, referring to Republicans' pledge to balance the budget and shrink the deficit. "Enough is enough, if you want to go to war, start paying for it." 
The Pentagon's 2012 budget projected the department would need $661 billion in fiscal 2016, according to a summary of the budget released by the department.  
R epublicans on the Senate Budget Committee bolstered the Overseas Contingency Operations (OCO) by $38 billion last week. Rubio said Tuesday that while he respects the committee's work, he believes senators need to debate defense spending. 
"I respect the work they've done, and ultimately, that might be where we wind up," Rubio said from the Senate floor, but he added that senators need "a serious debate" on defense spending.
