Secret Service A federal appeals court heard arguments today on whether Secret Service agents have a special privilege that allows them to refuse to testify about the president. Independent Counsel Kenneth Starr is trying to get testimony from agents on whether President Clinton and Monica Lewinsky were ever alone together in a study off the Oval Office. The Secret Service says if agents have to testify, presidents will not allow them to be close enough to guard effectively. The independent counsel says no privilege allowing agents to refuse to testify has ever been recognized, and only Congress should create it, not the courts. NPR's Steve Inskeep reports.
