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.

Following a break, Judge Merchan told the parties that he had worked through his own notes and asked the lawyers for each side to weigh in on what he might have missed.

The defense sought an instruction about former President Trump regarding bias.

"We don't think that this is necessary, this charge," prosecutor Josh Steinglass said in response. "I don't think instructing the jury that they shouldn't hold bias against the defendant is necessary -- voir dire has satisfied this problem, I think."

The defense also sought an instruction that hush money payments are not inherently illegal. Prosecutors opposed it, arguing the request amounts to the judge making the defense argument for them.

Defense attorney Emil Bove also asked for an instruction that "hush money is not illegal."

"What the defense is asking," Colangelo responded, "is for you to make their argument for them."

The judge agreed with Colangelo, saying that including that language would be "taking it too far."

"I don't think it's necessary," Merchan said.
