Ratings giant sees potential threat to the US credit rating

The ongoing failure of lawmakers to reach a consensus on the debt ceiling negotiations, forced Fitch Ratings to put the government's 'AAA' rating on negative ratings watch. CNBC explains:

"Although Fitch continues to believe that the debt ceiling will be raised soon, the political brinkmanship and reduced financing flexibility could increase the risk of a U.S. default," the rating agency wrote in a statement.
