FBI Director James Comey has caused consternation with his public actions. Everyone is trying to understand what's really going on behind the scenes. One explanation, I believe, is that Comey is at war with the Department of Justice.

The FBI's responsibility is to investigate. However, they can only do that if they get help from the DOJ. Lacking such cooperation, the FBI is put in an awkward position where they cannot fully proceed and complete their investigation.

This would explain why, in July, Comey went public and made the case for possible crimes by Hillary Clinton, but also said, "No reasonable prosecutor would bring such a case." This public position was inconsistent, baffling Congress and the public. Put in an impossible position by the DOJ, Comey felt he had to disclose what he considered damning evidence while at the same time trying to send the message that "he could not find a reasonable prosecutor to bring the case." His subsequent testimony to Congress reinforces such an interpretation.

Fast forward to the most recent disclosure by Comey. Leaks indicated that Comey was having difficulty getting a search warrant to examine Huma Abedin's emails. It appears that the FBI's New York office first discovered the existence of such emails as part of their separate investigation into Anthony Weiner's sexting.

It seems reasonable that Comey was unofficially informed of the content of Abedin's emails, which reinforced his earlier concern that crimes may have been committed. Once again blocked by the DOJ, the only thing Comey could do was to go public and, in what looks like a call for help, indicate that there was a need to pursue his investigation. As a result of going public, two days later Comey was granted a search warrant by the DOJ that he previously could not obtain.

Comey, I feel, is a person of character. It is hard to believe he has suddenly gone rogue. It is more plausible that the public is observing a man who is trying to prevent a DOJ cover-up. If Clinton wins on Nov. 8, the cover-up will most likely continue. If she loses, we will find out exactly what was going on and the process of seeking justice will proceed.

If there is no wrongdoing, the DOJ should have no problem cooperating fully with the FBI's investigations.

The Obama administration wants Clinton to win. The active campaigning by President Obama and first lady Michelle Obama on behalf of Clinton is unusual and reinforces the view that much more than an election is at stake. Obama and Clinton have much to lose if they have been active participants in a cover-up. If it's found that a cover-up extends into the White House, reputations will be forever damaged, or worse, if there are future prosecutions.

The stakes this Tuesday have never been higher: whether or not we are a nation of laws.
