Except for him using a newspaper as a primary source, I like that letter! Why, it almost sounded like someone was being taken to the woodshed..or at least the woodshed is getting cleared out with a new shaving strop added.
Primary source was the OIG report. The news accounts corroborate the OIG report. See first full paragraph on page 2, which says that, as well as the previous substance of the letter, which goes into more detail about the contents of each source.
The press will just bury this. Heck, it took the NK progress mostly negative!
