The Washington Post’s Walter Pincus and Jim VandeHei playing Chopsticks again…….

Wonder who the stranger is? Homeless person? Tourist? Betty Crocker? Sally Quinn?

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.”
