With court resuming after the lunch break, Michael Cohen has retaken the stand for cross-examination by the defense.

Questioning has gotten off to a combative start.

"You know who I am, don't you?" defense attorney Todd Blanche asked Cohen.

"I do," Cohen said.

"In fact on April 23 you went on TikTok and called me a crying little s--- didn't you?"

"Sounds like something I would say," Cohen said, prompting some laughter in the overflow room.

The prosecution objected, prompting a conference at the bench.

The question was stricken from the record and cross-examination resumed.

Michael Cohen testified about the fallout from his work for Trump, telling the jury he is no longer a lawyer.

"I lost my law license as a direct result of this," he said.

He said he wrote his book, "Disloyal," to "pass the time" in prison, then wrote his second book, "Revenge," which he described as a "forensic dissection of the prosecution ... against a critic of the president."

The jury then saw a 2023 social media post by Donald Trump about "convicted liar and felon" Michael Cohen.

Prosecutor Susan Hoffinger questioned Cohen about Trump suing him in Florida for half a billion dollars -- and for the first time in a while, Trump, at the defense table, opened his eyes, took notes, and passed them to his attorney Todd Blanche.

Cohen told the jury that he regrets what he did for Trump.

"I regret doing things for him that I should not have. Lying. Bullying people in order to effectuate a goal," Cohen said. "I don't regret working with the Trump Organization, as I expressed before some very interesting great times."

"But to keep the loyalty and do things that he had asked me to do -- I violated my moral compass, and I suffered the penalty, as has my family," Cohen said.

Trump appeared to have his eyes closed for the majority of Cohen's last answer. The prosecution completed its direct examination of Cohen, and the court recessed the lunch.

Michael Cohen said that after he pleaded guilty to campaign finance charges related to the Stormy Daniels payment -- as well as other tax charges -- he served 13 months in federal prison before being sent to home confinement during the COVID-19 pandemic.

Trump, sitting at the defense table, had his eyes closed as Cohen testified about his time in prison.

Cohen then testified that he was sent back to prison after he declined to sign an agreement that would have prohibited him from speaking or writing publicly.

"Didn't seem like a federal document," Cohen said, adding that it did not include any numbers and included several typos.

Cohen suggested he was sent to solitary confinement around the time he was writing his book, prompting a sustained objection from defense lawyers.

Asked about the tax charges, Cohen told jurors that while he agrees his tax filings had an "error," he believes he was treated unfairly by prosecutors.

"I have constantly maintained that I did not dispute the fact there was an error in the taxable amount -- in the tax that was due," Cohen said.

"What I did dispute, and I continue to dispute, is for a first-time offender … never having been audited, that this would go immediately to a criminal charge. From the day that we found out, I was given 48 hours within which to plead guilty" -- or face an eighty-page indictment that would have included charges against his wife, he said.

"And I was going to protect my wife," Cohen said.

Michael Cohen told the jury about his 2018 guilty plea for campaign finance violations related to the Stormy Daniels payment, as well as other tax evasion charges.

"What was that day like for you?" prosecutor Susan Hoffinger asked.

"Worst day of my life," Cohen said.

The jury then saw the tweets that then-President Trump posted in August 2018 following Cohen's guilty pleas.

"If anyone is looking for a good lawyer, I would strongly suggest that you don't retain the services of Michael Cohen!" one said.

"It caused a lot of angst, anxiety," Cohen said about the tweets.

Asked to describe his understanding of Trump's message, Cohen said, "Certainly displeasure. That I no longer was important to the fold."

Trump, at the defense table, leaned forward to read his own tweets as they appeared on the monitor.

Cohen told jurors that he reported to federal prison on May 6, 2019. He told the jury he was sentenced to three years in prison, followed by three years of supervised release.

"I apologized to Congress, I apologized to the country, I apologized to my family" in congressional testimony in February 2019 before he reported to prison, because "the citizenry had a right to know in order to make a determination about the individual who was seeking the highest office in the land," he said.

Following the mid-morning break, prosecutor Susan Hoffinger resumed her direct examination by asking Cohen about attorney Robert Costello, who represented him in 2018.

Cohen testified that Costello told him "this would be a great way to have a backchannel of communication to the president in order to ensure you're still good and still secure"

Cohen said that Costello also touted his relationship with Rudy Giuliani, who was close with Trump at the time.

Costello suggested his representation would be "very beneficial for you going forward with this matter."

Cohen said he was skeptical of Costello because he seemed "really sketchy and wrong."

Cohen also said worried that "anything I said to him was going to be spoken and told to Rudy Giuliani."

Jurors saw an April 2018 email from Costello to Cohen, which Cohen said was sent to "reinforce the whole concept of the back channel."

"I am sure you saw the news that Rudy is joining the Trump legal team. I told you my relationship with Rudy which could be very useful to you," Costello wrote in the email.
