Whitewater independent counsel Kenneth Starr today vowed to move quickly and get to the truth in investigating whether President Clinton told a former White House intern to lie about an alleged affair with him. Starr's investigation of the Whitewater land deal has expanded over the years to cover other areas. Under the Independent Counsel law, the Attorney General can decide whether to expand an existing investigation, or hand it over to a new independent counsel. The matter does not have to be related to the issue the counsel is already investigating. NPR's Chitra Ragavan reports.
