29 Sep 2008 12:37 pmAndrew Sullivan breathlessly asks: "What is CBS withholding?"

He's picking up on a report by Howie Kurtz that CBS is holding "two more responses on tape that will likely prove embarrassing."

I don't know about the content, but what Kurtz is referring to, according to a network insider briefed on the coverage plans, is Palin's answers for Katie Couric's "Vice Presidential Questions" series.

The questions and answers will air on Wednesday and Thursday, the source said.
