Countering Bill Nelson, Marco Rubio Will Oppose Debt Deal in Senate

Bucking the party line, Sen. Marco Rubio, R-Fla., will vote against the debt deal.

Rubio spokesman Alex Burgos did not elaborate on Rubio's decision, saying more information is coming.

But Rubio's no-vote -- which will counter Sen. Bill Nelson's support for the debt-deficit package -- could signal growing trouble for Republican and Democratic leaders hoping for quick congressional approval today.
