Story highlights Chris Christie participated in an interview with WFAN Radio in New York

The New Jersey governor responded to lewd comments Donald Trump made

Washington (CNN) One of Donald Trump's closest advisers was a no-show at his debate Sunday night, and now we have a clearer understanding of why.

New Jersey Gov. Chris Christie revealed Tuesday morning that he was not happy with the way Trump responded after tape of his 2005 lewd and sexually aggressive comments broke Friday night.

"I was there when he found out about it and there's no question in my mind he's embarrassed by it," Christie said during an interview with WFAN Radio in New York. "But I think that he should have been much more direct and much more focused on saying, just saying 'I'm sorry and only I'm sorry and that's what I would have done.'"

Christie told the radio hosts that he had "issues to deal with in New Jersey" Sunday, which prevented him from appearing at the debate. But sources had told CNN that Christie was upset that Trump wouldn't listen as they were in crisis management mode. Ultimately, Trump did not just say he was sorry, but he tried to turn the tables by bringing allegations against Bill Clinton into it.

"On the video itself, let's be really clear it is completely indefensible and I won't defend it and haven't defended it," Christie said.
