On redirect examination, prosecutor Susan Hoffinger asked Michael Cohen about his testimony on cross-examination that nondisclosure agreements are perfectly legal and that the contract with Stormy Daniels was also legal.

Hoffinger sought to emphasize how out of the ordinary this particular NDA was.

"Under the circumstances of this NDA with Stormy Daniels -- was that perfectly legal under those circumstances?" Hoffinger asked, referring to efforts to affect the 2016 election.

"No ma'am," Cohen said.

On redirect examination, Michael Cohen offered some context about how he claims he inadvertently provided some fake case law to the court during a recent bid to end his supervised release.

"I went onto Google Bard which is an AI search engine," Cohen said. "It gave me a plethora of cases that appeared to me to be legitimate. They certainly looked legitimate and there were facts behind it and supported what we were going to put in the upcoming motion."

"I was just trying to be helpful," Cohen added.

But when Cohen showed the cases to his current lawyer, she noticed they were "not legitimate."

At her recommendation, Cohen said he notified the court about the fake cases.

Michael Cohen testified under redirect examination that he had nothing at stake in the outcome of Trump's criminal trial.

"Are you actually on trial here?" Hoffinger asked.

"No ma'am," Cohen said.

"Are you a witness here?" Hoffinger asked.

"I am," Cohen said.

"Are you charged with any crimes here?" Hoffinger asked.

"No ma'am," Cohen said.

While Cohen was subpoenaed to testify at this trial, he described his outlook about the trial as markedly different from his participation and plea in a 2018 federal investigation.

"My life was on the line. My liberty. I was the defendant in the case," Cohen said.

On redirect examination, Michael Cohen provided some background on the $30,000 he said he stole from the Trump Organization by overcharging them for work he did with Red Finch -- funds that were paid to him as part of the Stormy Daniels reimbursement payment.

"Red Finch is a technology company that I had asked to assist in a CNBC poll, and the poll was regarding the most famous businessmen in, like, the last century," Cohen said, speaking to the jury. "Mr. Trump's name was on that list and at the beginning of this poll he was polling toward the very bottom. It upset him, so he had me come to his office and he provided me with a sheet of paper."

"I reached out to Red Finch who told me he was able to create an algorithm to ensure that Mr. Trump would rise and rise significantly in this poll. We talked about what number Mr. Trump wanted to finish," Cohen said.

The jury sat in rapt attention as Cohen spoke.

Eventually Trump came in No. 9 but he declined to pay Red Finch because CNBC didn't bother following through with the poll, Cohen said. Cohen ended up paying them -- in a brown paper bag in cash, he said.

"You felt some pressure to make some payment to your friend? Hoffinger asked.

"Yes," Cohen responded.

Asked why he did it, Cohen said, "Well for a long time I had been telling him about the $50,000. ... I was angered because of the reduction in the bonus, and so I just felt it was almost like self help."

"I wasn't going to let him have the benefit this way as well," Cohen said, admitting that it was wrong.

Donald Trump said Wednesday that he didn't take the stand in his hush money trial because he didn't agree with the judge's rulings -- and because he was seemingly worried about information that could have come out during cross-examination.

"He made rulings that makes it very difficult to testify," Trump said in an interview on WABC Radio, referring to Judge Juan Merchan. "Anything I did, anything I did in the past, they can bring everything up, and you know what, I've had a great past -- but anything."

"The other reason is because they have no case," Trump said. "In other words, why would -- why testify when they have no case?"

Trump had originally indicated he would testify, saying on April 12 that "I would testify, absolutely." But he subsequently appeared to back away from the idea, falsely telling reporters on May 2 that the limited gag order in the case -- which prohibits extrajudicial statements about witnesses and jurors -- prevented him from testifying.

The next day in court, Judge Merchan directly addressed Trump to clarify that he has an "absolute right" to testify and that the limited gag order does not apply to his statements in court.

"I want to stress, Mr. Trump, that you have an absolute right to testify at trial, if that is what you decide to do after consultation with your attorneys," Merchan said.
