The latest word is that not only did Berger lose documents, but he also added some to the files:

…the thrust of the federal investigation now looking into Mr. Berger’s actions should center not necessarily on what was taken from the archived files but what was placed in them.

Trying to rewrite a little history?

And this part is very disturbing, at least to me:

…adding an entirely new layer of intrigue to the story is word that telephone calls made by Berger during those latter two visits may have been monitored by an “unauthorized agency.”
