Activist Investor, Carl Icahn is at it again. This time he's pressuring Family Dollar Stores (FDO) to 'Sell itself' and with no time to waste. In a letter to the company's CEO, Mr. Icahn says "It is imperative that Family Dollar be put up for sale immediately." Just earlier this month, Icahn revealed he holds nearly 10 percent stake in the company making him the largest shareholder. Icahn says he's made his preference clear and if Family Dollar resists selling itself, his last resort would be to replace the company's entire board. The letter comes after a conversation between Icahn and Family Dollar's CEO the evening before. TheStreet's Susannah Lee has the details.
