Defense attorney Todd Blanche tried to downplay prosecutors' theory of the case and emphasized that Cohen was Trump's attorney in 2017 and that the $35,000 paid each month over that year was Trump paying him for his services.

"Take a step back. Nobody disputes that Mr. Cohen was President Trump's lawyer in 2017," Blanche said. "So what makes more sense, that president was paying his personal attorney in 2017 the $35,000 per an agreement he made with his personal attorney?... Or the version that Mr Cohen said?"

Blanche then mimicked Cohen's testimony, as Michael Cohen:

"No, I was not paid, I was going to work for free ... I'll just work for free and make a lot of money as a consultant," Blanche said, mimicking Cohen.

"For the first time in President Trump's life, he decided to pay me back triple," Blanche continued, mimicking Cohen. "He doubled up the $130,000, he gave me $50,000 for some online poll -- by the way, I stole from him a little bit on that -- and I decided I wanted a bigger bonus. That's what really happened, ladies and gentlemen.

"There's a reason why in life usually the simplest answer is the right one -- and that's certainly the case here," Blanche said.

Defense attorney Todd Blanche attacked Michael Cohen's testimony that he did not work under a retainer agreement for Trump, as referenced in the invoices.

"There was a retainer agreement, and that's how retainer agreements work," Blanche said, referring to Cohen's testimony. "Anything criminal about that?"

"That's not evidence of some secret agreement that Mr. Cohen had with President Trump. He broadcasted this to the world," Blanche continued. "This was not a secret. Michael Cohen was President Trump's personal attorney -- period."

Pulling up a transcript in which Cohen testified there was never expected to be a retainer agreement, Blanche said, That was a lie," stretching out each word.

"A lie is a lie, and this is a significant lie," he said.

As Blanche argued about the practice of "verbal retainer agreements," prosecutor Joshua Steinglass objected twice. Judge Merchan overruled both.

Defense attorney Todd Blanche tells jurors they will have to find two things to convict: "First, that the documents contained false entries, and second, that President Trump acted with an intent to defraud."

Blanche argued that Michael Cohen did legal work for Trump in 2017, making his invoices for legal services -- which he submitted for reimbursement of the Stormy Daniels payment -- legitimate requests for payment.

"Cohen was rendering services to President Trump in 2017 as his personal attorney," Blanche argued, highlighting parts of Cohen's testimony about his role and work for Trump.

Cohen testified that he served as Trump's personal attorney for free, but Blanche is attempting to suggest that the invoices at the center of the case were Cohen's way of getting payment in 2017.

"Cohen lied to you. Cohen lied to you on direct examination," Blanche said.

"It's a paper case," defense attorney Todd Blanche says. "This case is not about an encounter with Stormy Daniels 18 years ago. An encounter that President Trump has unequivocally and repeatedly denied ever occurred. It's not even about a settlement in 2016," Blanche said.

"The bookings were accurate. And there was absolutely no intent to defraud," he said. "And beyond that, there was no conspiracy to influence the 2016 election."

Starting a PowerPoint showing the evidence, Blanche quickly seeks to made the case a referendum on the credibility of Michael Cohen, telling jurors he lied on the witness stand.

"You cannot convict President Trump of any crime beyond a reasonable doubt on the words of Michael Cohen," Blanche said.

"He told you a number of things on that witness stand that were lies, pure and simple," Blanche continued.

"The words that Michael Cohen said to you on that stand -- they matter. He took an oath, he swore to tell the truth, and he told you a number of things on that witness stand that were lies, pure and simple," Blanche said.

Judge Merchan told the jury that they have the ultimate authority in determining the truthfulness of a witness' testimony -- an instruction that might come in handy given the emphasis that defense lawyers placed on Michael Cohen's testimony, which they say includes lies.

"You will alone determine the truthfully and the accuracy of the testimony of each witness," Merchan said.

He added that the jury could either disregard the testimony of an untruthful witness entirely, or disregard part of it.

"There is no particular formula" to determine credibility, Merchan said.

"You may consider whether the witness has any interest in the outcome of the case," he said -- another matter that might weigh on jurors' minds.

"You may consider whether a witness did have, or did not have, a motive to lie," the judge said.

Trump's attorney had told the jury Cohen had an "axe to grind" against his former boss. Prosecutors partially conceded that Cohen had a motive, acknowledging that, to date, he is the only one who suffered any consequences from the matter at hand.

Trump, at the defense table, appeared to look over to the jury and offer a bit of a closed-mouth grin.
