CNN's Kyra Phillips got caught dissing her sister-in-law with her mic on, when she thought she was off-air during a Bush speech.
Video and transcript at Newsbusters.
My favorite part:
Phillips: "Brother–of course, brothers have to be, you know, protective. Except for mine. I’ve got to be protective of him."
[unidentified woman–unintelligible]
Phillips: "Yeah. He’s married, three kids, but his wife is just a control freak."
[unidentified woman #2]: "Kyra."
Phillips: "Yeah, baby?"
[unidentified woman #2]: "Your mic is on. Turn it off. It’s been on the air."
I just would have loved to see the look on her face, poor thing.
