The dog ate my homework?!

We'll that's close to the White house's excuse when asked about the loss of an undetermined number of e-mails concerning official White House business. The Washington Post reports:

The White House acknowledged yesterday that e-mails dealing with official government business, possibly including missives related to the firing of eight U.S. attorneys, may have been lost because they were improperly sent through private accounts intended to be used for political activities.

I find myself asking how does this implicate the Presidential Records Act or Waxman’s earlier direction to not delete any emails or other electronic correspondence?

UsaToday reports that the White House has promised to review its staffers' e-mails

...for anything relevant to the prosecutors' dismissal... [and that] ...it would provide documents to the Senate and House Judiciary committees as long as they are not internal communications, but exchanges with people outside the White House.

My question is why not "internal communications" bearing in mind that Rove and several of his deputies were said to have these RNC email accounts and I imagine it would be reasonable to assume would have communicated between each other using them?

I imagine some very pointed questions will be asked about why Rove who allegedly uses his Blackberry to conduct most of his e-mailing still has a security clearance bearing in mind that Blackjacking has already been demonstrated to bypass enterprise security defenses?

National security? What National Security?
