House Intelligence Committee Chair Rep. Michael Turner and House GOP Conference Chair Rep. Elise Stefanik have requested that the Department of Justice investigate Michael Cohen for perjury following his testimony in the trial last month.

During his trial testimony, Cohen said that he lied to the House Permanent Select Committee on Intelligence in 2019 when he said that Donald Trump and Allen Weisselberg did not ask him to inflate Trump's personal statement.

"So, you lied under oath in February of 2019? Is that your testimony?" defense attorney Alina Habba asked in court.

"Yes," Cohen responded.

Shown his 2019 testimony in court, Cohen subsequently reversed himself and said that his 2019 testimony was truthful, explaining the contradiction by clarifying that Trump speaks like a "mob boss" and that he indirectly asked for his statement to be inflated.

In a letter to Attorney General Merrick Garland sent today, Stefanik and Turner requested that the Department of Justice open an investigation into Cohen potentially committing perjury.

"That Mr. Cohen was willing to openly and brazenly state at trial that he lied to Congress on this specific issue is startling," they wrote. "His willingness to make such a statement alone should necessitate an investigation."

Last week, Stefanik sent a separate judicial complaint to the New York State Commission on Judicial Conduct related to the conduct of the judge overseeing Trump's trial. In a statement to ABC News, a court representative said in response that the judge's actions "speak for themselves."

Donald Trump's lawyers abruptly stopped the testimony of their first expert witness -- who was expected to testify for a full day or two -- after Judge Engoron limited the topic areas of his testimony.

Steven Witkoff, a real estate investor and longtime friend of Trump's, was brought into court by the defense team to testify that Trump's Doral golf club was undervalued in Trump's financial statements.

But Judge Engoron sustained an objection from the state barring any testimony about the valuation of Doral, significantly limiting Witkoff's testimony and appearing to hamper the defense strategy proposed by Trump's attorney Chris Kise.

Kise argued that the inaccuracies in Trump's statement of financial condition can cut both ways: Even if some properties were overvalued, other properties like Doral were significantly undervalued and balanced out the statement, according to Kise.

"It is highly, extraordinarily relevant if there are assets that are undervalued substantially on those same statements," Kise said. "They can't look at this one-sided."

State attorney Andrew Amer fiercely rebutted that argument, telling Engoron he should not take the defense's position that the inconsistencies "come out in the wash."

That argument appeared to convince Engoron, who said that overvaluations would not "insulate" a false valuation. He promised to sustain any objection that related to the value of Doral -- an approach Kise described as "lunacy."

"The reader of the financial statement has the right to know whether each particular number was accurate," Engoron said. "They are looking for accuracy."

As court got underway this morning, Judge Engoron -- who has said he has received harassing messages regarding his role in the trial -- did not address Trump's sharing of a post on his Truth Social platform calling for his arrest.

The former president yesterday shared a user's post calling for the "citizens arrest" of Engoron and Attorney General Letitia James "for blatant election interference and harassment."

When he expanded the case's limited gag order earlier this month, Engoron said that his chambers had received hundreds of "harassing and threatening phone calls, voicemails, emails, letters, and packages" since the start of the trial.

The gag order does not prohibit attacks against Engoron himself or the New York attorney general.

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?'"

One week ahead of her planned testimony, Ivanka Trump has appealed Judge Engoron's decision to require her to testify in person at the Trump Organization's fraud trial.

Ivanka Trump's lawyer Bennet Moskowitz asked an appellate court to decide whether Engoron has jurisdiction to compel her testimony and whether the trial subpoenas issued by the New York attorney general were properly served.

Ivanka Trump, who is not a defendant in the case, is currently scheduled to testify next Wednesday as the final witness in the attorney general's case before the defense presents its case.
