That's the incident I was referring to - do you know the source and if it's been confirmed as Larry Johnson?
In a strange twist in the investigation, the grand jury -- acting on a tip from Wilson -- has questioned a person who approached Novak on Pennsylvania Avenue on July 8, 2003, six days before his column appeared in The Post and other publications, Wilson said in an interview. The person, whom Wilson declined to identify to The Post, asked Novak about the "yellow cake" uranium matter and then about Wilson, Wilson said. He first revealed that conversation in a book he wrote last year. In the book, he said that he tried to reach Novak on July 8, and that they finally connected on July 10. In that conversation, Wilson said that he did not confirm his wife worked for the CIA but that Novak told him he had obtained the information from a "CIA source."
Novak told the person that Wilson's wife worked for the CIA as a specialist in weapons of mass destruction and had arranged her husband's trip to Niger, Wilson said. Unknown to Novak, the person was a friend of Wilson and reported the conversation to him, Wilson said.
