Cohen told jurors that he began working for Trump after helping Trump with a series of legal favors.

"We ended up overtaking the board and resolving the issue which was to Mr. Trump's satisfaction," Cohen said about the first favor related to a board at a Trump property. "He liked the way that occurred and then continued to ask me if I would assist in other legal issues or matters he had."

"Did he pay you for that work?" prosecutor Susan Hoffinger said.

"No, ma'am," Cohen said

According to Cohen, Trump offered him a job after he presented Trump a $100,000 bill for legal costs related to the earlier favors.

"Would you want to come work for me?" Cohen recounted Trump saying. "I was honored, I was taken by surprise, and I agreed"

When asked about the $100,000 legal bill, Cohen said Trump "asked if I would like to get fired on the first day." The bill was never paid, according to Cohen, who immediately left his law firm to work for the Trump Organization as Trump's special counsel and a senior vice president.

When asked about the kind of work Cohen did for Trump, Cohen responded, "It was whatever concerned him -- whatever he wanted."

Cohen said he reported "just to Mr. Trump."

Michael Cohen briefly introduced himself to the jury, telling them how his father immigrated to California after surviving the Holocaust.

"Four children later, here I am," Cohen said about his parents.

Cohen told the jury that he went to law school at the urging of his family, though he did not want to practice law.

"I wanted to go to Wall Street," Cohen said.

He briefly explained how he acquired wealth with real estate investments and taxi medallions.

"I ended up going into business with a friend of mine who had grown up with me and we started purchasing buildings," Cohen said.

Cohen stood up in the witness box so he could identify Trump in the courtroom.

"He is wearing a blue and white tie," Cohen said while looking toward Trump.

"The people call Michael Cohen," prosecutor Susan Hoffinger said.

Michael Cohen entered the courtroom and took his seat in the witness box.

Donald Trump stared straight forward as Cohen walked into the courtroom. He did not appear to look toward Cohen.

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.

Prosecutors introduced text messages between Michael Cohen and his daughter related to Cohen not being considered for Trump's chief of staff after Trump won the 2016 election.

"My daughter and I are very close -- we are very much connected and she was concerned that I was upset that I was not being considered for the role," Cohen said. "I explained to her that there are so many opportunities."

By December 2016, Cohen said, he was "beyond angry." His Trump Organization bonus had been cut by two-thirds.

"I was truly insulted, personally hurt. Didn't understand it," Cohen said of his feelings. "It made no sense, after all that I had gone through in terms of the campaign as well as things at the Trump Organization, and laying out $130,000 on his behalf to protect him."

"It was insulting that the gratitude shown back to me was to cut the bonus by two-thirds," Cohen said.

Cohen said he was "truly pissed off and angry," he recalled telling then-CFO Allen Weisselberg.

At that point, Cohen had not been paid back for the Daniels advance and expressed as much to Weisselberg.

"The best that you get for extending yourself as I did is to have your bonus cut by two-thirds?" Cohen recalled saying. He said Weisselberg responded by saying, "We'll make this right."

Trump, at the defense table, showed no reaction as Cohen recounted his emotional response to having his bonus cut.
