Judge Juan Merchan took his seat on the bench and opened the day's proceedings.

Each of the lawyers made brief introductions before Merchan addressed Trump in his usual fashion.

"Good morning, Mr. Trump," Merchan said from the bench.

Donald Trump has entered the courtroom. He looked around the room as he made his way to the front.

The former president is joined by his attorneys, as well as numerous associates and Secret Service.

Eric Trump and attorney Alina Habba are seated together in the first row, immediately behind Trump. Behind them in the second row, which is completely full, are Trump's legal adviser Boris Epshteyn, Natalie Harp, and J.D. Vance.

Campaign team members Jason Miller and Karoline Levitt are seated in the very back of the courtroom.

Manhattan District Attorney Alvin Bragg has also entered the courtroom.

Prosecutors from the Manhattan district attorney's office have entered the courtroom.

Prosecutor Susan Hoffinger, who is expected to lead Michael Cohen's direct examination, placed a hefty three-inch binder at the lectern before returning to the counsel table.

The courtroom in the Manhattan Criminal Courthouse is packed with reporters and security ahead of Michael Cohen's testimony.

Approximately 70 reporters are crammed into the gallery of the courtroom, seated on wooden benches that seat six per row. Five members of the public are seated in the back of the gallery behind the prosecution counsel table and jury box, and five court officers are scattered throughout the courtroom.

On the right side of the courtroom, earlier witnesses Jaden Jarmel-Schneider and Georgia Longstreet are seated near computer monitors. Both work as paralegals for the Manhattan district attorney's office and testified as part of the prosecution's case.

Jarmel-Schneider introduced phone records and a summary exhibit about the falsified documents into evidence, while Longstreet introduced Trump's social media posts into evidence.

After affirming he worked on "The Apprentice" and did personal work for Trump and members of his family, Michael Cohen confirmed he has never had a retainer agreement with Trump or his company.

"In the whole time you worked for the Trump Organization, you never had a retainer agreement?" defense attorney Todd Blanche asked.

"I never had a retainer agreement," Cohen said.

"And you never had a retainer agreement with any of those individuals, did you?" Blanche asked.

"Correct, Cohen answered.

"And the reason why you didn't have a retainer agreement is because you didn't need one?" Blanche asked. "You knew you were going to get paid?"

"Yes," Cohen said.

"You didn't have to worry when you did personal work for Donald Trump Jr. about the retainer agreement because you were getting paid by the Trump Organization, correct?" Blanche said.

"Correct," Cohen replied.

Blanche suggested there was "nothing wrong" with Cohen never having retainer agreement -- including when Cohen submitted invoices for legal work in 2017. At that time in 2017, Cohen was working as a private lawyer for Trump, separate from the Trump Organization.

Prosecutors have argued that Trump falsified records when he paid Cohen for legal services pursuant to a retainer agreement in 2017.

Blanche subsequently concluded his questioning for the day, with Cohen's cross-examination scheduled to continue on Monday.

Cohen did not look at Trump when he exited the courtroom.
