Rajat Gupta, the former Goldman Sachs Group Inc. director charged with insider trading as part of the Galleon Group LLC probe, asked a judge to dismiss some of the counts against him. The government's indictment focuses on two instances in which the U.S. said Galleon co-founder Raj Rajaratnam traded on information he allegedly received from Gupta, though it "improperly uses those two instances to create five purportedly separate substantive securities-fraud charges," according to Gupta's filing in federal court in Manhattan.
