Following the conclusion of the state's direct examination of Michael Cohen, Trump attorney Alina Habba has begun what is expected to be a lengthy cross-examination.

“You understand what 'under oath' means?” Habba asked Cohen at the start of her cross-examination.

“Yes,” Cohen said, after which Habba began to describe Cohen’s previous criminal conduct.

When Donald Trump attempted to bid for the Buffalo Bills football team in 2014, he claimed that his net worth was "in excess of eight billion dollars," according to a document entered evidence during Michael Cohen's testimony.

To support the bid, Trump's frequent lender Deutsche Bank sent a letter to Morgan Stanley to demonstrate that Trump had the "financial wherewithal" to support his bid, according to Cohen.

The New York attorney general alleges that Trump used his inflated financial statement to convince Deutsche Bank to support Trump's financial strength.

The line of questioning prompted strong objections from Trump lawyer Chris Kise, who argued that the bid for the Buffalo Bills is not related to any of the attorney general's causes of action.

"I think this is arguably false, particularly the eight billion dollars ... and this shows a pattern of practice of fraud," Judge Engoron said when overruling the objection.

Donald Trump used his inflated financial statements to convince journalists about his net worth, to lower his insurance premiums, and even to support his bid to purchase the Buffalo Bills football team, according to Michael Cohen.

Cohen described how the Trump Organization would grant external parties only limited access to the documents themselves, often presenting them during video calls -- rather than handing out the document for external parties to keep -- in the process of demonstrating Trump's net worth.

For example, Cohen described using the documents in a meeting with a journalist from real estate news site "The Real Deal" to "create the story about how much Trump was actually worth," Cohen said.

According to Cohen, Trump Organization executives used Trump's financial statements in meetings with insurance companies to obtain lower premiums, and Trump would occasionally attend these meetings to help move the process along.

"About three quarters of the way through the meeting, Mr. Trump would then come in, and there would be an extended conversion about his net worth, and that he was richer than the insurance companies," Cohen testified, adding that Trump's drop-in to the meeting was pre-planned.

Trump's financial statement also proved vital when Trump attempted to get a line of credit for a 2014 bid to purchase the Buffalo Bills, according to Cohen.

"We can all agree that Mr. Trump never owned the Buffalo Bills," Judge Engoron remarked.

Sitting at the witness stand in a white dress shirt and sport coat, Cohen swapped his reading glasses on and off as he studied financial statements presented to him.

Feet away at the counsel table, Trump leaned forward to study the real-time transcript of Cohen's testimony while actively whispering and passing notes between his lawyers Alina Habba and Chris Kise.

Often leaning to speak with his lawyers on either side of him, Trump appeared actively engaged throughout Cohen's testimony since the mid-day break.

While Cohen testified steadily and confidently for most of his early-afternoon testimony, he at times spoke vaguely and struggled to offer specific firsthand knowledge. When asked about Trump's adult children, Ivanka, Don Jr. and Eric, he initially described them as involved in the process of inflating specific assets before walking back his testimony.

"I did not observe them specifically engaging in conversation," about that, Cohen acknowledged.

After testifying on and off for five hours, Donald Trump has stepped down from the witness stand after completing his direct examination.

State attorney Kevin Wallace concluded his questions by asking Trump about his former CFO Allen Weisselberg, who pleaded guilty to tax evasion, and about internal controls at the Trump Organization.

Weisselberg served three months for tax fraud after he pleaded guilty to 15 felony charges related to his compensation while working for Trump.

"People went after him viciously and violently because he worked for me," Trump said.

Trump said he only learned about Weisselberg's illegal conduct because of the Manhattan district attorney's criminal probe into the Trump Organization and Weisselberg.

"I feel very badly for him," Trump said. "He did a good job for me for a long time."

Regarding the current court case, Wallace asked, "Do you think anything needs to change at the Trump Organization because of what you learned from this lawsuit?"

"I don't think so," Trump said, but suggested he would defer to his new accounting firm.

"We will see if anything will come of it," he said.
