Because neither Woodward nor the administration official who leaked the information to him wanted to appear before the grand jury. Woodward had publicly criticized the investigation as a witch hunt and said it was all about nothing. Woodward was bound by agreement with his Administration source so he couldnt go to Fitzgerald. Then around Nov 3, Woodwards administration source went to the Prosecutor and reported the conversation. Then Fitz had Woodward testify Nov 14. Woodward would never have come out if he hadnt been outed by his administration source.
Thanks for the information. I didn't know that. I figured it was another RAT attempt to replay watergate like they aretrying to replay Vietnam.
