That and the reporters Fitzgerald pulled in during the Libby case and another case. Also after Fitzgerald success several other federal prosecutors pulled in reporters. There was one about steroids if I remember correctly. The reporter talked because they didn’t want to go to jail in contempt.
In another age the whole journalistic community would rally around a journalist who refused to name a source or other information in court. If the reporter went to jail he became a hero to his peers and even to the public. Today the establishment news media is in such public disrepute, no one cares.
