I heard the interview.
Brokaw referred to vague statements said during the campaign, to which Liberman said he regretted.
Brokaw wanted Liberman to give an apology — but Liberman stuck to his statement that he had regrets, as do most people for some of the things they say during a campaign.
There was never any exact thing — just “some statements”.
I was watching K-K-K-Katie the other night (please don't ask...it wasn't my TV) and she said that Lieberman had suggested that Hussein was a Marxist.Perhaps that's one of them.
