Following insider trading charges brought in May, former Bradley Arant Boult Cummings and Foley & Lardner partner Walter “Chet” Little formally denied the allegations in court on Thursday, entering a not-guilty plea alongside a co-defendant in the criminal case.

Little faces criminal charges that he profited from options and stock trades based on confidential information related to a number of Foley & Lardner’s clients, including Oshkosh Corp., Whiting Petroleum Corp. and Harley-Davidson Inc., according to the complaint brought against him by the Manhattan U.S. Attorney’s Office. Little also faces allegations that he passed information to a neighbor, Andrew Berke, who allegedly used it to trade.
