Former President Trump is not expected to take the stand in his criminal hush money trial, sources familiar with the matter tell ABC News.

It's possible that Trump could make a last-minute decision to testify, so sources caution that nothing is final until the defense rests its case.

Trump's lawyers have indicated publicly that Robert Costello, Michael Cohen's one-time legal adviser, is expected to be their last witness before they rest their case today.

Prosecutor Susan Hoffinger, with Michael Cohen back on the stand, played an Oct. 16, 2017, recording that Cohen secretly made of a conversation with Stormy Daniels' then-attorney Keith Davidson regardin the Stormy Daniels payment.

"What would you do if you were me?" Cohen is heard asking on the recording.

"Ugh. I can't even -- I don't even know. ... I can't even imagine," says Davidson.

"I mean, would you write a book, would you break away from the entire Trump, you know, we'll call it doctrine, you know, would you go completely rouge, would you join with Bannon, you know. What -- I mean any -- any thoughts?" Cohen asks.

"Because it's not just me that's now being affected. It is my entire family. It's, you know -- and the --- there's no -- nobody is thinking about Michael. You understand? And despite what like -- for example, you know, what the earlier conversation, you know, and who else would do that for somebody, who else?" he says on the recording.

" I did [it], because I care about that guy and I wasn't going to play pennywise, pound foolish," COhen says, to which Davidson replied, "Right."

"And I'm sitting there and I'm saying to myself, what about me?" says Cohen. "And I can't --- I can't even tell you how many times he said to me, you know, 'I hate the fact that we did it.' And my comment to him was, "But every person that you've spoken to told you it was the right move."

Asked by Hoffinger about the recording, Cohen said, "I was referring to the payment that I made to Keith Davidson that I made on behalf of Mr. Trump."

"How has telling the truth about what you did with Mr. Trump affected you?" Hoffinger asked.

"My entire life has been turned upside down. I lost my law license, my businesses, my financial security, which I was fortunate early to be able to obtain. My family's happiness is paramount," said Cohen.
