Prosecutors called Daniel Dixon, who works as a lead compliance analyst at AT&T, to testify as a custodian of records about cell phone data.

Prosecutors used his testimony to enter into evidence phone records for Michael Cohen's company phone that jurors will likely see later when Cohen testifies.

As Dixon testified, Trump leaned forward in his chair with a yellow highlighter in hand, flipping through and marking up a stack of papers.

Defense attorney Emil Bove then did a detailed cross-examination of Dixon, as part of an effort to cast any possible doubt on records related to Cohen.

Dixon then stepped off the stand, with he and Trump exchanging tight smiles as he passed the defense table.

During a short redirect examination, Trump White House aide Madeleine Westerhout confirmed that she currently works as the chief of staff for Robert C. O'Brien, who served as Trump's national security adviser from 2019 to 2021.

Westerhout then concluded her testimony.

She and Trump both smiled at each other as she stepped off the witness stand. As she passed by the defense table, Trump whispered what appeared to be a brief word of thanks to her.

Defense attorney Necheles concluded her cross-examination of Trump White House aide Madeleine Westerhout by asking Westerhout about Trump's reaction to the 2018 Wall Street Journal story about the Stormy Daniels hush money payment.

Westerhout confirmed she spoke with Trump after the story came out and recalled that "he was very upset by it."

"Why?" Necheles asked.

"My understanding is he knew it would be hurtful to his family," Westerhout said.

Part of her testimony about Trump's response was struck from the record because Westerhout could not recall Trump specifically mentioning his family.

"I could just tell that the whole situation was unpleasant," Westerhout said.

Defense attorney Susan Necheles suggested that the practice of not mailing Trump's personal items directly to the White House -- including checks for him to sign -- was a standard practice used by past presidents to quickly get their personal mail.

"It was a way that items could be sent to you and you could get them promptly to President Trump?" Necheles asked Trump White House aide Madeleine Westerhout, suggesting that security practices delayed mail sent to the White House and that packages might get lost.

"That's right," Westerhout said.

"This was a problem [that] … exists for everybody who is in that office?" Necheles later asked, suggesting past administrations used a similar solution.

"I don't have any knowledge of what is was like in previous administrations, but I can't imagine it would have been any different," said Westerhout.

Necheles also sought to contradict the prosecution's contention that Trump personally reviewed every check he signed.

"You said he signed a tremendous amount of documents ... commissions, proclamations, executive orders, memos, letters ... hundreds of documents a day?" Necheles asked Westerhout.

"Not every day, but sometimes," Westerhout said.

"Sometimes he would sign checks without reviewing them?" Necheles asked.

"Yes," said Westerhout.

Judge Merchan communicated a bit of a warning to Michael Cohen ahead of his planned testimony next week, telling prosecutors to ask him to stop talking about the case after Trump's team brought up his continued out-of-court statements.

"I would direct the people to communicate to Mr. Cohen that the judge is asking him to refrain from making any more statements about this case," Merchan said.

"That comes from the bench and you are communicating that on behalf of the bench," said the judge.

Merchan's rebuke came after defense attorney Todd Blanche brought up recent statements by Cohen, including his appearing on TikTok this week wearing a shirt with a photo of Trump behind bars.

"It's becoming a problem every single day that President Trump is not allowed to respond to this witness," Blanche urged. "He has stated on social media that he is going to stop talking, and he doesn't," Blanche said of Cohen.

Prosecutors said they had already "repeatedly" asked Cohen and others not to post about the case, but claimed they had no control over the witnesses.

Trump, at the defense table, grinned broadly during the exchange regarding Cohen and his behavior on social media. But he shook his head and looked at Blanche, seemingly in disbelief, when Merchan -- instead of ordering Cohen to stop -- merely asked prosecutors to speak to him.

Court was subsequently adjourned for the week.
