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.

Defense attorney Todd Blanche continued to work to paint a picture of Michael Cohen as a proven liar who pleaded guilty to crimes associated with those lies and leveraged his cooperation as part of those plea deals to secure a shorter prison sentence.

"When you plead guilty to a crime, one of the things you get -- one of the benefits you get -- is a little time off your sentence ... correct?" Blanche asked.

Blanche then said that in the case of Cohen's guilty plea to charges that included those related to the Stormy Daniels payment, "You got that credit even though you lied."

Cohen, for his part, has claimed some responsibility for the hush money charges Donald Trump now faces -- but he has suggested that he himself should not have been charged, and that the system that charged him was "corrupt."

"Do you have any doubt in your mind that the outcome of this trial affects you personally?" Blanche asked Cohen.

"Yes," Cohen replied.
