Trump trial: Stormy Daniels tells (almost) all about alleged encounter with Trump

Jurors were shown a photo of the cover of Trump's 2004 book, "How to Get Rich: Big Deals from the Star of The Apprentice."

"How many times does the word 'Trump' appear on the cover of this book?" a prosecutor asked Penguin Random House VP Sally Franklin, on the witness stand.

"Three times," Franklin said.

ABC News previously reported about prosecutors' plan to use the quotes from Trump's books against him at trial.

"When somebody hurts you, just go after them as viciously and as violently as you can," Franklin read from the book. "For many years I've said that if someone screws you, screw them back."

Prosecutors have called Sally Franklin as their first witness.

Franklin works as senior vice president for Penguin Random House.

She is testifying as a custodial witness.

Trump attorney Susan Necheles began the proceedings by renewing their request that Judge Juan Merchan preclude parts of Stormy Daniels' planned testimony.

Necheles said that Daniels is expected to be the second witness today.

Prosecutor Susan Hoffinger argued that the context of the alleged 2006 sexual encounter between Daniels and Trump are important, though Daniels will not testify about that in detail.

"The details of the encounter, your honor, are important," said Susan Hoffinger. "In terms of a sexual act, it will be very basic ... how she came to have sex and how she felt about it."

"There is just no need for those kinds of details here," Necheles argued. "This case is a case about books and records, and we shouldn't get into how she felt about it, what happened in the room."

Judge Juan Merchan said he would stick with his earlier ruling allowing the testimony, but acknowledged that Daniels had "credibility issues."

"We don't need to know the details of the intercourse," Merchan said. "I agree with you that she had credibility issues."

Trump has denied that he had a sexual encounter with Daniels.

Proceedings are underway for Day 13 of Donald Trump's criminal trial in what is expected to be a dramatic day in the courtroom with the expected testimony of Stormy Daniels.

Trump is, as usual, seated at the defense table alongside his attorneys.

Todd Blanche and Susan Necheles flank the former president, and Emil Bove is at the far end of the table.
