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.

Donald Trump has entered the courtroom, looking at members of the press as he entered.

He is joined by his son Eric Trump and attorney Alina Habba.

In addition to approximately 70 members of the press in the courtroom, six members of the public are present in the courtroom to watch today's testimony.

They said they learned about the opportunity to watch the trial over the last few weeks and decided to come see the testimony for themselves. Some traveled from Los Angeles, Philadelphia, New Jersey and Brooklyn to attend the trial.

A court officer repeatedly reminded them not to fall asleep in the courtroom.

Prosecutors for the Manhattan district attorney's office have arrived in the courtroom.

District Attorney Alvin Bragg is not present at this point.

Stormy Daniels testified that she starred in her first adult film at 23 after she traveled to Los Angeles with a friend.

She said she was a background actor in a film when a producer from Wicked Films approached her. Within days she had her first contract.

"I was honestly kind of scared to do it," Daniels said.

Daniels testified about her work producing adult films. She said she has produced over 150 films and won multiple awards.

"I was one of the youngest -- if not the youngest -- featured director," Daniels said.

She also said she was in music videos for Maroon 5 and acted in "The 40-Year-Old Virgin" and "Knocked Up."

Prosecutor Susan Hoffinger asked Daniels twice to slow the pace of her delivery after she raced through her film credentials.
