In his cross-examination of expert witness Douglas Daus, defense attorney Emil Bove asked Daus why the 2016 Trump-Cohen recording on Cohen's phone abruptly cuts off, attempting to raise doubts about the integrity of the recording.

Daus suggested that he heard in the recording that another call was coming in, but Daus said he could not say with certainty why the recording ended.

"You don't have firsthand knowledge of why it cuts off?" Bove said.

Bove -- a former prosecutor with plenty of experience handling cellphone extractions -- then discussed with Daus the different ways to extract a device. For a brief moment, the tone of the cross-examination shifted from tense to friendly.

Judge Merchan subsequently ended the proceedings for the day, dismissing the parties.

The proceedings are scheduled to resume tomorrow at 9:30 p.m. ET.

Expert witness Douglas Daus testified about a recording on Michael Cohen's phone from Sept. 6, 2016, at 10:56 a.m.

The recording, approximately two minutes long, captures a conversation between Cohen and Trump.

"I need to open up a company for the transfer for all of that info regarding our friend David," Cohen says on the call. "I am all over that, and I spoke to Allen about it when it comes time for the financing," Cohen says.

"What financing?" Trump asks.

"We'll have to pay him something," Cohen said.

The prosecution then concluded its direct examination of Daus.

On cross-examination, defense attorney Emil Bove sought to raise doubts about the integrity of the material on Cohen's phone, suggesting it had been "subject to the risk of manipulation" somewhere in the chain of custody.

Expert witness Douglas Daus walked jurors through what he found on Cohen's phones after he extracted the data -- including an astounding 39,745 contacts.

Most phones have a few hundred contacts, Daus said.

On one of Cohen's phones, he had 10 pages of contacts for Donald Trump alone, according to Daus.

On Cohen's second phone, he had 385 contacts, which is average, according to Daus.

Daus then displayed for the jury text messages between Cohen and former White House Communications Director Hope Hicks.

"Call me," Cohen texted Hicks on November 4, 2016.

Jurors then saw a photo of Cohen in the White House briefing room which was contained on his phone. Cohen is standing behind the podium in the photo.

Jurors also saw a calendar entry on Cohen's phone called "Meeting with POTUS" on February 8, 2017.

Daus identified that Cohen's phone contained three encrypted messaging apps: WhatsApp, Telegram, and Signal.

Less than an hour after jurors listened to some of Cohen's recordings of his phone calls with Keith Davidson, Daus showed the jurors the location of some of those recordings on Cohen's phone.

Prosecutors have called their next witness: Douglas Daus, who works for the lab that processes devices for the Manhattan district attorney's office.

Daus works as an analyst in the unit of the Manhattan DA's office that handles intake and processing of electronic devices, such as a cell phone seized pursuant to a search warrant. Daus said the unit creates "extractions" of the devices, which are copies of the devices called a Cellebrite or GreyKey report.

The extraction contain "anything that is normally on a phone," according to Daus, including text messages, contacts, call history, and software.

The extraction also includes metadata, which provides a deeper record of when, where, and how a device was used.

For the Trump case, Daus conducted an analysis of two of Michael Cohen's phones -- an iPhone 6S and iPhone 7.

Daus said Cohen consented to the analysis of the devices.

Prosecutor Christopher Conroy told Judge Merchan during the contempt hearing that the limited gag order exists because of Trump's "persistent and escalating rhetoric" regarding trial participants, adding that Trump had violated the gag order nine times already.

"He has done it again here," Conroy said.

"That is what the order forbids, and he did it anyway," Conroy said about Trump's remarks about the composition of the jury.

Conroy then turned his attention to Trump's remarks about witness and former National Enquirer publisher David Pecker last Thursday at a construction site in midtown Manhattan, in which he said, "He's been very nice. I mean, he's been -- David's been very nice. A nice guy."

"It was deliberate and calculated," Conroy said, describing the remarks as a "deliberate shots across the bow" to participants in the case.

"The defendant thinks the rules should be different for him," Conroy says about Trump's remarks about witnesses like Michael Cohen and David Pecker.

Trump has defended some of his commentary about the trial as a recitation of what he sees in media coverage. But Conroy said that Trump's rhetoric carries an "air of menace that is substantially different" than a news report.

"He places this process and proceeding here in jeopardy," Conroy said,
