Cover-Up Mode

Orcinus summarizes recent developments on other briefings to GW Bush besides the infamous smoking memo. Most interesting to me is the stuff at the end, discussing how the administration is abusing the classification procedures. The national interest certainly may be damaged by the release of sensitive information about the content of a briefing. But once the info is out, how is the national (as opposed to political) interest hurt by releasing the names of the recipients of a memo?
