As part of a series of video, jurors were shown a video of an October 2016 Trump rally in Gettysburg, Pennsylvania

"They are trying to poison the mind of the American voter. Every woman lied when they came forward to hurt my campaign," Trump said in the video.

Lastly, jurors sew a brief video of a press conference by President-elect Trump praising Michael Cohen.

Trump, in one of the videos, appears to acknowledge how damaging the stories could have been to his election prospects.

"If 5% of the people think its true, and maybe 10% of the people, we don't win," Trump says in the speech.

In the courtroom, Trump's demeanor completely changed immediately after the videos were played for the jury. He perked up and frantically whispered with his attorney Todd Blanche, looking displeased.

Browning, the C-SPAN executive, concluded his testimony, and defense lawyers opted not to cross-examine him.

As Robert Browning took the witness stand, Trump was slumped back in his chair, sunken quite low down, with an entirely blank expression on his face. Then his eyes appeared to close.

Browning, a C-SPAN executive is testifying about four videos from 2016: two from Trump campaign events in North Carolina, one from Pennsylvania, and one from a news conference. The executive was called to testify because Trump's defense declined to stipulate that it is, in fact, Trump in the videos

Jurors were first shown a video from a Trump rally in Greensboro, North Carolina, in October 2016.

“I have no idea who these women are. I have no idea,” Trump says in the video regarding allegations of infidelity. “The stories are total fiction. They are 100% made up. They never happened. They never would happen.”

Judge Juan Merchan has ruled from the bench that prosecutors will be permitted to introduce evidence about Trump's alleged "intimidation effort" for a limited purpose.

Prosecutors can use the evidence to offset the defense claim that witnesses are financially benefiting from the trial and explain why some witnesses have changed their story; however, the evidence cannot be used to demonstrate Trump's "consciousness of guilt," as the prosecution had sought.

Merchan also said jurors will have May 24 -- the Friday before Memorial Day -- off, because a juror has to catch a flight at 11 a.m. ET.

Prosecutors then called as their next witness Robert Browning, who has worked as the executive director of the C-SPAN's archives for 30 years.

Jurors have re-entered the courtroom following the mid-morning break.

Trump returned to the courtroom speaking with his defense attorney Todd Blanche as he entered.

Judge Juan Merchan lightly scolded Blanche about running late.

"Let's try to keep the break short," Merchan told Blanche, reminding him that jurors are waiting. "Let's do better."

Exiting the courtroom following the day's testimony, former President Trump reiterated claims that the case is unfair and that he should be campaigning instead of sitting in court.

"I'm sitting here because that's exactly what they want," Trump said. "They don't want me on the campaign trail. But it's a real -- a real disgrace and the whole world is watching. It's a disgrace to New York."

Trump also railed against the limited gag order in the case, for which the judge this morning fined him $9,000 and ordered him to remove nine social media posts.

"This gag order is not only unique, it's totally unconstitutional," Trump opined, calling Judge Merchan "conflicted."

Asked by a reporter what he meant by "conflicted," Trump brusquely turned to respond.

"You can figure that one out easily," he said.
