Judge Merchan began by denying the state's request to enter into evidence former Trump Organization CFO Allen Weisselberg's separation agreement with the company.

"It would come in as a business record, but I am not going to allow it in," Merchan said. "It doesn't prove any element of the offense, it doesn't move the ball in any way."

Prosecutors sought to introduce the agreement -- which allotted Weisselberg $2 million after he left the Trump Organization-- to explain why Weisselberg was not testifying at the trial. Weisselberg is currently serving a five-month sentence on Rikers Island for perjury.

Trump, meanwhile, has been waiting patients at the defense table for the jury to enter, which is taking a bit longer than usual.

"Where's the jury?" one individual in his entourage could be heard whispering.

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.

When Donald Trump won the 2016 election, Cohen testified there was no role for him in the incoming administration.

"My service was no longer necessary," Cohen said.

He was offered a position in the White House as "assistant general counsel" by Reince Preibus, but turned it down. He said he was disappointed he was not considered for chief of staff.

"I didn't want the role. I didn't believe the role was right for me or that I was even competent to be chief of staff. I just wanted my name to be included," he testified.

"It was more about my ego than anything," Cohen said about his disappointment. "I would have liked to have been considered."

Cohen said he pitched being "personal attorney to the president." He would need the role, Cohen said, because there were "outstanding matters" to be dealt with. Cohen conceded it would have helped him personally and professionally.

"I also had another thought in mind, which was consulting. That's what I really wanted because that afforded me the time to stay at home, in New York," he said.

Cohen testified it could have been lucrative to help people understand Trump's thinking.

"Mr. Trump was an enigma," Cohen said. "Because of my close proximity to him for a decade, I did understand."

"Did you think you could monetize being personal attorney to the president?" prosecutor Susan Hoffinger asked.

"Absolutely," Cohen said.

Trump's eyes remained closed during this portion of the testimony.
