April 23 (Bloomberg) -- Berkshire Hathaway Inc. Director Thomas Murphy talks with Bloomberg's Betty Liu about Berkshire Chief Executive Officer Warren Buffett's investment in Goldman Sachs Group Inc. after the U.S. Securities and Exchange Commission sued the bank for fraud. Buffett injected $5 billion into Goldman Sachs in 2008, and remains comfortable with his investment, Murphy said, citing a telephone conversation with Buffett. The SEC has accused Goldman Sachs and an employee of misleading clients on the sale of mortgage-related investments. (Source: Bloomberg)
