Lynch. During 2008 Goldman Sachs received criticism for an apparent revolving door relationship, in which its employees and consultants moved in and out of high-level U.S. Government positions, creating the potential for conflicts of interest and leading to the moniker "Government Sachs". Former Treasury Secretary Henry Paulson and former United States Senator and former Governor of New Jersey Jon Corzine are former CEOs of Goldman Sachs along with current governor Murphy. Additional controversy attended the selection of former Goldman Sachs lobbyist Mark A. Patterson as chief of staff to Treasury Secretary Timothy Geithner, despite President Barack Obama's campaign promise that he would limit the influence of lobbyists in his administration. In February 2011, the Washington Examiner reported that Goldman Sachs was "the company from which Obama raised the most money in 2008", and that its "CEO Lloyd Blankfein has visited the White House 10 times". Insider trading cases In 1986, Goldman Sachs investment banker David Brown pleaded guilty to charges of passing inside information on a takeover deal that eventually was provided to Ivan Boesky. In 1989, Robert M. Freeman, who was a senior Partner, who was the Head of Risk Arbitrage, and who was a protégé of Robert Rubin, pleaded guilty to insider trading, for his own account and for the firm's account. Rajat Gupta insider trading case In April 2010, Goldman director Rajat Gupta was named in an insider-trading case. It was said Gupta had "tipped off a hedge-fund billionaire", Raj Rajaratnam of Galleon Group, about the $5 billion Berkshire Hathaway investment in Goldman during the financial crisis of 2007-2008. According to the report, Gupta had told Goldman the month before his involvement became public that he wouldn't seek re-election as a director. In early 2011, with the delayed Rajaratnam criminal trial about to begin, the United States Securities and Exchange Commission (SEC) announced civil charges against Gupta covering the Berkshire investment as well as confidential quarterly earnings information from Goldman and Procter & Gamble (P&G). Gupta was a board member at P&G until voluntarily resigning the day of the SEC announcement after the charges were announced. "Gupta was an investor in some of the Galleon hedge funds when he passed the information along, and he had other business interests with Rajaratnam that were potentially lucrative... Rajaratnam used the information from Gupta to illegally profit in hedge fund trades... The information on Goldman made Rajaratnam's funds $17 million
