NEW YORK—An unidentified lawyer and lobbyist revealed Monday that a "sniveling yellow streak" led him to anonymously divulge U.S. State Department misconduct. "I am a blubbering cream puff with no guts whatsoever," said the source, 44, who wished to remain anonymous. "People should know what officials are doing, but I'm a big baby, and I can't risk my job or reputation by revealing my identity." The source spoke to reporters in a dark parking garage, then disappeared into the blackness.
