Defense attorney Todd Blanche opened today's questioning by asked Cohen about his communication with reporters.

"Since that time [when your last testimony ended], how many reporters have you talked to?" Blanche asked.

Cohen said he's spoken to reporters "who called to say hello, to see how I'm doing," but that he didn't talk about the case.

"Didn't speak at all about your testimony last week?" Blanche asked.

"Correct," Cohen responded.

As Cohen resumed his testimony, jurors appeared attentive, with several taking notes. Trump sat slouched at his chair with his eyes closed.

Following the break, former Trump attorney Michael Cohen has entered the courtroom.

He took his seat in the witness box to resume his cross-examination as Trump looked on.

Defense attorney Todd Blanche asked to approach the bench about an ongoing discovery issue.

Both legal teams leaned in as Blanche spoke to the judge.

With the sidebar completed, the judge called for a ten-minute break.

Judge Merchan denied a request from defense lawyers to broaden the scope of testimony from their expert witness Bradley Smith, who is an expert on campaign finance regulations.

On Thursday, defense lawyers asked Merchan to allow Smith to testify about various terms related to federal campaign finance laws. Merchan denied the request, citing long standing precedent prohibiting witness testimony about the law.

"An expert is not permitted to present or interpret the law," Merchan said.

Merchan also expressed concerns about Smith's testimony prompting a "battle of the experts" between Smith and an expert called by prosecutors, which Merchan said would confuse the jury.

Merchan said that Smith could still testify, as long as he follows the limits imposed in his pretrial ruling on the case's motions in limine.

"The court will monitor this testimony closely to ensure full compliance," Merchan said in a pretrial ruling. "Any deviation from this ruling could result in sanction up to and including striking the expert's entire testimony."

Trump, sitting at the defense table, shook his head after the judge announced his ruling.

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.
