Nearly everyone commenting on the rapidly expanding Petraeus story is missing the most critical point:  it is inconceivable that the FBI would get involved in an investigation that came to include the Director of Central Intelligence even peripherally without having that information go straight up to the desk of FBI Director Robert Mueller. And Mueller would undoubtedly inform Attorney General Eric Holder five seconds later, if only to cover his own behind. As this investigation implicated Petraeus in a case of adultery, at a minimum, some weeks ago, suggesting the possibility of major political fallout, there was clearly a cover-up or deliberate delaying action by either Mueller or Holder or both. Or, if the president was informed, by the White House itself to avoid a scandal just before the election. This could easily have been perceived as something that might alter the course of the election, and perhaps it would have.
