We can't know that Berger's purposes in removing the documents were political, but it is really easy to believe that they were.
Sorry. When I said "catching" I should have said "releasing the information about catching." My argument stands.
re: TimingIt seems a bit off to assume there was a Republican political desire to leak the info now. It would best be used later like say during the convention or some other time. At this point the information happens, Berger gets burned and a replacement is found, no harm, no foul. Some people think the timing was such since the commision is going to report their findings it was better for the news to come out now rather afterwards. Otherwise it gives more ammo to opponents since something like this would taint the findings and they'd prefer people talking about the report rather than about leaked documents.
