Former President Trump appeared to have a visible reaction when the DA's office called his longtime executive assistant to the stand, and he craned his chin up as she stepped up. He half-smiled, almost sadly.

When exhibits were put on the screen during Graff's brief testimony, Trump leaned entirely forward toward the monitor on his table, squinting to see the documents.

When Trump's attorney said to Graff, "You don't want to be here, do you?" Graff responded, "That's correct." Trump attorney Todd Blanche laughed, but Trump did not.

At the end of Graff's testimony, when she got off the stand and made her way past Trump, he did something he hasn't done yet: He stood up from his seat to greet her, appearing to try to shake her hand.

After longtime Trump assistant Rhona Graff testified that she vaguely recalled seeing Stormy Daniels on in the reception area on the 26th floor of Trump Tower, defense attorney Trump sought to reframe Graff's testimony as innocuous -- suggesting to Graff that Daniels was spotted in Trump Tower because she was being considered for a role on Trump's TV show, "The Apprentice."

Graff, from the witness stand, confirmed that she was aware through "office chatter" that Daniels was being considered for the show. She said that Trump was frequently on the hunt for "celebrities who were colorful, or interesting" to "bring new juice to the show."

As part of those musings, Graff said she became aware that Daniels was being considered.

"I vaguely recall hearing him say that she may be one of the interesting people who could be on the show," Graff testified.

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.

The first witness prosecutors with the Manhattan DA's office plan to call is former National Enquirer publisher David Pecker, according to two sources familiar with the matter.

ABC News previously reported that prosecutors planned to call Pecker as a witness, but sources now say he's expected to be the first witness to take the stand.

Pecker served as the longtime chief executive of American Media Inc., which published the National Enquirer.

Shortly after Trump announced his 2016 presidential campaign, Pecker met with Trump and agreed to act as the "eyes and ears" of the campaign by looking out for and killing negative stories about Trump, according to the Manhattan DA.

As part of the arrangement, Pecker allegedly directed a deal to pay $30,000 to a former Trump Tower doorman regarding the false allegation that Trump allegedly fathered a child out of wedlock, prosecutors say. Then-Trump attorney Michael Cohen allegedly insisted that the deal stay in place even after AMI discovered the allegation was false, and AMI paid the doorman, according to the Manhattan DA.
