Chris Christie said Donald Trump was 'embarrassed' by his hot mic comments that ignited a political firestorm since Friday, though the New Jersey governor has no plans to jump ship.

'I'm still supporting Donald,' he said Tuesday morning on the 'Boomer and Carton' sports radio talk show. 'I'm really upset about what I heard, but in the end this election is about bigger issues.

This is the first time since the lewd recording came to light Friday, that Christie, one of Trump's most vehement supporters, spoke out – admitting that he had been in the room when the candidate found out that the Washington Post had published the 11-year-old video.

New Jersey Gov. Chris Christie (left) says he hasn't stopped supporting Donald Trump (right), but he was 'really upset' when he heard the billionaire's tawdry comments from 2005

Chris Christie, seen here at the first presidential debate, wasn't seen at the second, which aroused suspicion that he might be ditching The Donald like some of his GOP peers

'Let's be really clear,' he told the New York City-based radio hosts. 'It is completely indefensible and I won't defend it and haven't defended it. That kind of talk and conversation, even in private, is just unacceptable.'

Christie said he advised Trump to apologize, quickly, for the comments.

'I made that very clear to Donald on Friday when this first came out and urged him to be contrite and apologetic because that's what he needs to be,' Christie said.

Trump dished to Access Hollywood host Billy Bush while on board a bus as he was mic-ed up about making moves on a married woman like a 'b****' and being able to kiss and grab women 'by the p****' because of his celebrity.

The New Jersey governor commented, 'this is just stuff that you just can't, can't be involved in and shouldn't even be thinking.'

After the video was released, Trump made a statement where he apologized, but turned the tables and pointed fingers at Bill Clinton for the ex-president's actual misdeeds.

Trump also dealt with the scandal onstage at Sunday night's presidential debate, though he tried to wrangle the news cycle back by trotting out four women who said they were victimized by the Clintons, three of whom say they were groped or worse by the former president.

From the tape's release on, mainstream Republicans have been distancing themselves from their party's nominee.

Christie expressed that he didn't blame them.

'Obviously I was disappointed by what happened and disappointed, in some respects, by the response initially, but I'm still supporting him,' Christie said, adding, 'I'm not going to sit here and be critical of other people who make the decision that they don't want to support him.'

Christie was one of the first candidates who had vied for the White House alongside the non-traditional Trump to then get on board his campaign.

His most recent role has been to handle Trump's transition should the billionaire businessman win.

His absence from Sunday night's debate in St. Louis, Missouri raised eyebrows, with political watchers wondering if perhaps Christie had bailed on The Donald too.

Christie said he stayed on the East coast because he had pressing matters in New Jersey.
