S&P Puts 'Negative' Outlook on U.S. AAA Credit Rating

April 18 (Bloomberg) -- Standard & Poor's put a "negative" outlook on the U.S. AAA credit rating, citing rising budget deficits and debt. The ratings firm said there is "a material risk that U.S. policy makers might not reach an agreement on how to address medium-and long-term budgetary challenges by 2013." Bloomberg's Hans Nichols, Michael McKee and Peter Cook talk about the report with Carol Massar on Bloomberg Television's "In the Loop." (Source: Bloomberg)
