Warren Buffett says there�s no question that the United States� debt is still AAA and that he�s not changing his mind about Treasurys based on Standard & Poor�s downgrade.

�If anything, it may change my opinion on S&P,� the legendary investor said.

Buffett is a big shareholder in Moody�s, rival to S&P.

And Buffett is putting his money where his mouth is. As of June 30, Buffett�s Berkshire Hathaway had $47 billion in cash and equivalents. Buffett tells me that at least $40 billion of that is in U.S. Treasury bills. Not only that, Buffett says almost all of his own personal holdings in cash and equivalents are in T-bills as well.

�I wouldn�t dream of putting it anywhere else,� says Buffett, adding that at Berkshire, the only reason he�s sold U.S. Treasurys in the past is to buy stocks or make acquisitions. And Buffett says Berkshire is still buying T-bills, even though yields have fallen so low. �If I have to buy (Treasurys) at a zero percent yield�� , I will,� he says. �I don�t like it, but we�ll do it.
