Billy Ray Dale, former White House travel office chief, pleaded not guilty to embezzling money paid by the news media for travel with the president, and asked the judge for the right to subpoena records from Hillary Rodham Clinton and other White House officials to prove his innocence. Among the records sought are those of the late Vincent Foster, the deputy White House counsel who committed suicide. Dale is accused of wrongfully pocketing at least $33,297. "Mr. Dale never spent a penny of government money or media money," his attorney, Steven C. Tabackman, said outside court. Dale claims that records taken from the travel office will prove his innocence. The Clinton Administration, complaining of lax management of the travel office, fired Dale and the other six employees in May 1993.
