After working on his father's successful 1988 presidential campaign, Bush learned from fellow Yale alumnus William DeWitt, Jr., that family friend Eddie Chiles wanted to sell the Texas Rangers baseball franchise along with the new sports stadium; built on land acquired under eminent domain law and built under funding financed through taxpayers' funds backed by a bond issued for its debt. In April 1989, Bush assembled a group of investors from his father's close friends, including fellow fraternity brother Roland W. Betts; the group bought an 86% share of the Rangers for $75 million. Bush received a 2% share by investing $606,302, of which $500,000 was a bank loan. Against the advice of his counsel, Bush repaid the loan by selling $848,000 worth of stock in Harken Energy. Harken reported significant financial losses within a year of this sale, triggering allegations of insider trading. On March 27, 1992, the Securities and Exchange Commission concluded that Bush had a "preexisting plan" to sell, that Bush had a "relatively limited role in Harken management", and that it had not seen evidence of insider trading.
