document: Undercover Audio Reveals Rajaratnam 's Frantic Calls After Goldman-Buffett Tip Fund manager Raj Rajaratnam made $ 1 million in two minutes of frantic calls after receiving an inside tip about a big investment in Goldman Sachs at the height of the financial crisis , prosecutors said this week at the Galleon founder 's insider trading trial . In the biggest Wall Street insider trading case since the 1980s , U.S. prosecutors have persistently pressed phone tap evidence that Rajaratnam had a direct line to his friend and then Goldman Sachs director , Rajat Gupta , who leaked bank secrets to him . The trial is in its fourth week and could last until the end of April . On Wednesday , the Manhattan federal court jury heard another FBI phone tap to support government allegations Rajaratnam knew a day before it was announced in September 2008 that Goldman would receive a $ 5 billion investment from Warren Buffett 's Berkshire Hathaway . In the phone tap of a call on Sept. 24 , 2008 , between Rajaratnam and his personal Galleon trader , Ian Horowitz , he is heard describing his efforts the previous day to buy shares two minutes before the 4 p.m. stock market close . '' `` I got a call at 3:58 , right ? '' '' Rajaratnam said , referring to the September 23 conversation with Gupta about a Goldman board meeting that day . '' `` Saying something good might happen to Goldman , right ? '' '' But when he then called Galleon , the first trader he reached was unable to complete it . '' `` I , so I told Ananth to buy some , he was fucking around , he ca n't , you know . So I went to Gary and just buy me , right ? '' '' The full name of trader Ananth was not known and the other person was Gary Rosenbach , then a Galleon manager .
