An underwriter who worked on a Trump Organization insurance policy to cover legal expenses incurred by the firm's executives is scheduled to testify this morning.

Michael Holl, an underwriter at Tokio Marine HCC, worked on the Trump Organization's Directors and Officers insurance policy in 2016 and 2017, according to the New York attorney general.

With Donald Trump about to be inaugurated president at the time, the Trump Organization attempted to increase their policy's limit to $50,000,000, which was ten times higher than their previous limit, according to the attorney general.

"In response to specific questioning from the underwriters, the Trump Organization personnel represented that there was no material litigation or inquiry from anyone that could potentially lead to a claim under the D&O coverage," the state alleged in their complaint.

However, four months before that representation was made, Trump Organization executives learned about an ongoing investigation by the attorney general into the Trump Foundation as well as Trump family members, according to the complaint.

After a dramatic day in court yesterday -- including surprise testimony from Donald Trump, a $10,000 gag order violation fine, and inconsistent testimony from Michael Cohen -- both New York Attorney General Letitia James and the former president took to social media to describe the state of the trial.

"Their 'star' witness lied like a dog on the stand today," Trump wrote in a Truth Social post overnight.

In a video statement posted on X, formerly Twitter, James defended her case against Trump as a multi-year effort built on thousands of documents and hundreds of witnesses, rather than simply the testimony of Cohen.

"The defendants' counsel attempted and failed to discredit our entire case," James said.

Judge Arthur Engoron yesterday denied a motion from the defense to dismiss the case following the conclusion of Cohen's testimony, saying that Trump's former lawyer was not the case's "star witness."

"There's enough evidence in this case to fill this courtroom," Engoron quipped.

Following the adjournment of court for the day, Trump and New York Attorney General Letitia James offered contrasting views of the testimony of former Trump lawyer Michael Cohen.

Trump, speaking to reporters in a courthouse hallway, continued to claim that today was his Perry Mason moment.

"He was caught lying like no one has ever lied," he said of Cohen. "It was better than a Perry Mason moment, and that should be the end of the case."

The former president also criticized Judge Engoron for not ending the trial following Cohen's testimony, claiming he is being "railroaded."

"Any other judge, this would be the end of the case," Trump said.

James, speaking separately to reporters outside court, downplayed Cohen's importance to the case.

"It's also important to know that Michael Cohen is not the main witness," she said.

"His evidence has been corroborated by the mountains of evidence, enough evidence to fill the courtroom," the AG said, echoing a phrase Engoron used earlier.

Speaking outside after his testimony was complete and court was adjourned for the day, former Trump attorney Michael Cohen portrayed his testimony as successful and vital to holding Trump accountable, despite the contradictions in some of his answers.

Cohen maintained that he was not intimidated by Trump being in court during his testimony.

"When you looked him in the eye, Michael, what did you see?" ABC News reporter Aaron Katersky asked him.

"I saw a defeated man. I saw somebody that knows that it's the end of the Trump Organization," Cohen said.

Donald Trump's defense team plans to call their first of several expert witnesses to the stand today.

Steven Witkoff, a New York-based real estate investor and developer, is set to testify about his expert opinion that the Trump National Doral golf course in Miami was undervalued in Trump's financial statement, despite the attorney general's claim to the contrary.

The expert report Witkoff prepared for the case also criticized the finding from the state's expert regarding the value of Trump's 40 Wall Street property.

During a 2018 roundtable on tax reform, Trump called Witkoff a "pal" who he inspired to enter the real estate industry.

"You know, people don't realize Steve started out as a lawyer -- a very good lawyer, a top lawyer in New York. And then he said, 'I'm going to go into the real estate business because I can do this, too," Trump said. "He saw me do it, and he said, 'If Trump can do it, I guess I can do it, right?'"
