Dumb Redhead Joke

Arianna Huffington discovers what has been known to the blogosphere for some time now:

It's July 6, 2003, and Joe Wilson's now famous op-ed piece appears in the Times, raising the idea that the Bush administration has "manipulate[d]" and "twisted" intelligence "to exaggerate the Iraqi threat." ....So [Judy Miller] calls her friends in the intelligence community and asks, Who is this guy? She finds out he's married to a CIA agent. She then passes on the info about Mrs. Wilson to Scooter Libby (Newsday has identified a meeting Miller had on July 8 in Washington with an "unnamed government official"). Maybe Miller tells Rove too -- or Libby does. The White House hatchet men turn around and tell Novak and Cooper. The story gets out.
This is why Miller doesn't want to reveal her "source" at the White House -- because she was the source.

But, she gets it wrong. If, Miller is protecting a source, it is someone at the CIA. Perhaps someone married to a blabbermouth former diplomat.
