Well - There's The Problem -

Right There! "...16 U.S. intelligence agencies"! Sixteen; count'em. Sixteen bunches of paranoid (at least) psychotics (possibly), all dead set on keeping their comings and goings and doings a Deep Dark Secret. Cheney's speech contained omissions, misstatements.
As an aside, for those who wonder just how Nancy Pelosi ended up with her knickers in such a twist; "Briefings" from CIA ops, and others of similar ilk, are well designed to attract attention HERE! (We Need More Money), while shifting it away from HERE! (Pay No Attention To The Man With The Tongs And The Flaming Splinters).
Those who have sat through, or delivered, testimony in a government setting will know what I mean.
Which doesn't mean that the Speaker of the House should be excused for nop paying attention when the CIA tried to slip the Iron Duke past the committee.
