Buffett sees headwinds for rating agencies

NEW YORK (Reuters) - Warren Buffett said rating agencies should be affected for a long time by recent events, but it will be difficult for his Berkshire Hathaway Inc (BRKa.N) holding company to lighten up on its interest in Moody's Corp (MCO.N) because of the large size of its stake.

Buffett, speaking on CNBC, also said that he might buy a stake in another domestic drug company. Berkshire Hathaway owns shares of Johnson & Johnson (JNJ.N).
