From Holden:

I detect a pattern.

The Vice President’s Chief of Staff, Irving L. “Scooter” Libby, resigns after being indicted for perjury in the Valerie Plame investigation.

White House Procurement Officer David Safavian resigns and is immediately arrested, accused of lying and obstructing a criminal investigation into Republican lobbyist Jack Abramoff’s dealings with the federal government.

White House Domestic Policy Advisor Claude Allen resigns after being accused of scamming department stores out of thousands of dollars.

Interior Secretary Gale Norton resigns before Jack Abramoff’s March 29 sentencing hearing, in which his attorney has promised Jack will “name names”.

So, I ask you…

What did Trent Duffy do?

Occam’s razor, baby. Occam’s razor.
