Following revelations by Anonymous that HBGary Federal was developing a plan of Nixonian dirty tricks, with false identities, forged documents, and other disinformation, the CEO of HBGary Federal has been fired resigned:

Aaron Barr’s departure as CEO of HBGary Federal represented the latest twist for the company and its Sacramento affiliate, HBGary Inc. A spokeswoman for the Sacramento company confirmed the resignation.

According to numerous reports, Barr’s company, which is based in Colorado and Washington, D.C., proposed conducting a disinformation campaign against critics of the U.S. Chamber of Commerce. The plan was presented to the chamber’s law firm, but the chamber says it wasn’t aware of it.

The plan was aborted after the hacker group Anonymous stole tens of thousands of e-mails from both HBGary and HBGary Federal – and posted many of the messages on the Web.

And now Democratic members of Congress are calling for an investigation of these activities.

Of course, there won’t be an investigation in the House.  The Republicans are busy looking for a blue dress.
