Statement on U.S. Credit Rating

U.S. Sen. Bernie Sanders issued the following statement after Standard & Poor's lowered the U.S. government's AAA credit rating: 

"I find it interesting to see S&P so vigilant today in downgrading the U.S. credit rating. Where were they four years ago when they, and other credit rating agencies, helped cause this horrendous recession by providing AAA ratings to worthless sub-prime mortgage securities on behalf of Wall Street investment firms?  Where were they last December when Congress and the White House drove up the national debt by $700 billion by extending Bush's tax breaks for the rich?"
