(New York, NY)  --  Credit ratings agency Fitch Ratings is putting the nation's triple-A rating on rating watch negative. 

In a statement, Fitch said it still believes the nation's debt ceiling will be raised, but brinksmanship on Capitol Hill could increase the risk of a default.  The House and Senate are battling over bills to raise the debt ceiling in order to allow the government to borrow the money it needs to pay its bills.  A spokesperson for the Treasury Department says Fitch's decision reflects the urgent need for Congress to act to remove the threat of default.  

House Republicans are pushing for concessions for raising the debt ceiling.  The White House says the full faith and credit in the United States shouldn't be up for negotiation.
