It is usual for certain types of news to be released on Fridays, especially anything that the powers-that-be would prefer not widely discussed. So I am wondering if this is the reason that it is on a Friday that Judith Miller, the New York Times reporter imprisoned during the course of the Plame investigation, has agreed to testify after all.
Probably a red herring. The whole investigation has been full of red herrings, and I doubt that we have seen the end of them yet. But for what it's worth, here is what Miller herself says:
I am leaving jail today because my source has now voluntarily and personally released me from my promise of confidentiality regarding our conversations relating to the Wilson-Plame matter. My attorneys have also reached agreement with the Office of Special Counsel regarding the nature and scope of my testimony, which satisfies my obligation as a reporter to keep faith with my sources.
This enables me to appear before the Grand Jury tomorrow. I'll say nothing more until after my testimony. I do, however, want to thank The New York Times, and my husband, family and friends, for their unwavering support. I am also grateful to the many fellow journalists and citizens from the United States and around the world, who stood with me in fighting for the cause of the free flow of information. It was a source of strength through a difficult three months to know they understood what I did was to affirm one of my profession's highest principles.
