It turns out that Keith Kerr, retired Colonel., U.S. Army; retired Brigadier General, California National Reserve, who submitted a YouTube question about gays in the military, is actually a member of Hillary Clinton's Lesbian, Gay, Bisexual and Transexual Americans For Hillary Steering Committee. He's also part of a film production crew trying overturn the "Don't Ask, Don't Tell" policy.
UPDATE: In the final seconds of the post-debate coverage, Anderson Cooper acknowledges that CNN messed this up and states that CNN did not know that Kerr has a position within the Clinton campaign and that had they known, they would have disclosed the association. Here's that video.
UPDATE: Looks like Gen. Kerr was one of "148 Military Brass and Veteran Luminaries Endorse John Kerry for Commander-in-Chief"
UPDATE: Uh Oh! Looks like there are more plants. John Edwards and Barack Obama supporters plus a union activist.
Speaking of plants, did you catch last week's episode of The Hillquarters?
