Ambassador source of Corner email?

In an update to yesterday's post about an old email purporting to be from a Marine in Iraq posted at the National Review's blog The Corner, we find via TPM Muckraker that it's worse than we thought.

Over at the National Review's blog, The Corner, Cliff May apologizes for posting a year-old anonymous forwarded email as news. May, let's note, was an adviser to the James Baker-led Iraq Study Group.

In his defense, May says it was shared with him by another adviser to the ISG, a U.S. ambassador. All the ISG experts, May explains, "[are] on a list-serve where we circulate what we view as significant articles and argue over them." May says the ambassador had forwarded the year-old anonymous e-mail to the list.

As TPM Muckraker notes, this means an expert advising the Iraq Study Group sent the group an anonymous list serve email for them to argue about.

Oy. But don't forget, if you are a liberal and you are shrill, you are the problem.
