Surely. Cashill is wrong on this one. Pam Gellar’s been perpetuating the myth too, disappointingly.

Here’s the follow-up story to the original Washington Times article that started the whole mess. It clarifies that the cases, even though they were mentioned in the same article by the WT, are not related:

I have heard (see below) that Quarles was working with investigators because, though he was not himself the person at the Analyst Corp accused of the passport breach, he could identify said TAC employee.

According to Mr. [Jerome] Corsi, Harris had information related to the State Department employees who had breached Obama’s passport records and that he was cooperating with government officials.

But the article you link to only mentions that Sean McCormick, State Dept spokesman, states that the passport cases and the identity thefts are unrelated.

While they may be indeed unrelated, I am not inclined to take a State Department spokesman's word for anything.
