Donald Trump kept contact information for two women who alleged they had sexual relationships with him, his longtime executive assistant testified Friday as the trial's second witness.

After former National Enquirer publisher David Pecker concluded his historic testimony as the first witness in the first criminal trial of a former president, Graff, entered the courtroom with a cane. Trump turned to see her as she entered, but the two did not appear to make eye contact.

Graff's testimony appeared to be a pick-me-up for jurors, who had been listening to the same voice on the witness stand for the better part of four days.

Graff worked for the Trump Organization for 34 years, beginning in October 1987, and testified that she was responsible for keeping Trump's contacts and calendars. Graff said those contacts included Karen McDougal and Stormy Daniels

Graff testified that she created the contact entry for Karen McDougal that included two addresses, a cell phone number, and an email address.

Under questioning from prosecutor Susan Hoffinger, Graff testified she had also entered a contact for Stormy Daniels.

"It contains her mobile phone number," Graff said. "I have a vague recollection of seeing her in the reception area on the 26th floor."

Graff said she also knew Daniels was a porn star.

Prosecutors have called Donald Trump's longtime executive assistant Rhona Graff as their next witness.

Former National Enquirer publisher David Pecker stepped down from the witness stand after a brief re-cross examination.

Former National Enquirer publisher David Pecker retook his seat on the witness stand after lunch, and the jury appeared engaged when prosecutor Josh Steinglass asked Pecker to explain things directly to them. Pecker slightly turned to face the jury when answering.

After the defense, during cross-examination, tried to suggest Pecker didn't want to get involved in the Stormy Daniels story for business and reputational reasons, Steinglass asked him to clarify.

"I said to Michael Cohen that after paying for the doorman story and the Karen McDougal story I wasn't going to pay anything further and I wasn't a bank," Pecker testified. "I told (editor) Dylan Howard there is no possible way that I would buy the story for $120,000 and that I didn't want anything to do with a porn star."

Steinglass asked Pecker, "Why did you reach out to Michael Cohen" about Daniels' claim of a sexual liaison with Trump?

"Based on our original agreement, any stories regarding Mr. Trump that could be embarrassing, I would call Michael Cohen right away," Pecker said.

"You weren't going to print it? You weren't going to pay for it?" Steinglass asked.

"Correct," Pecker responded.

"But you were still going to fulfill your obligation to tell Michael Cohen about it? So the campaign could squash it?" asked Steinglass.

"Yes," Pecker responded.

As he has previously, former President Trump complained on social media this morning that his supporters were being kept from gathering outside the courthouse -- even though that's not the case.

"Security is that of Fort Knox, all so that MAGA will not be able to attend this trial," Trump posted before he entered the courtroom.

But a small group of his supporters demonstrated this morning undisturbed in the designated protest area in the park outside the courthouse, where they've gathered each day of the trial this week.
