Instead of leading with the Iowa caucuses, Wednesday’s "The Situation Room" began its broadcast covering attorney general Michael Mukasey’s decision to open an investigation into the destruction of interrogation tapes by the CIA. Host Wolf Blitzer, during a segment with CNN senior legal analyst Jeffrey Toobin, compared this investigation to the investigation by Patrick Fitzgerald that led to the obstruction of justice conviction of Scooter Libby. "Whenever they [Bush administration officials] have to go testify, whether before a grand jury or to the FBI, and tell what they know... they fall into that dangerous area where they might not necessarily tell the whole truth, and then they could be charged with a cover-up, if you will, sort of along the lines of Scooter Libby."
