Hedge fund founder and inside trader Raj Rajaratnam is also, apparently, a terrorist supporter. A recently uncovered 2007 investigation showed that Rajaratnam donated $2 million to the American branch of the separatist Tamil Tigers. Rajaratnam was also entangled with the Tigers in 2005 and 2006 when a charity he founded donated $3.5 million to a front group. Rajaratnam's lawyer, of course, denies any involvement with the Tamill Tigers, but he doesn't say whether the avowed hip hop lover is working on anything with M.I.A. [Dealbook/NYT]
