Seeking to painting a picture of the machinations behind what Michael Cohen called a "pressure campaign" to keep him in the Trump fold as investigators closed in on him, prosecutor Susan Hoffinger displayed an email from Michael Cohen's then-legal adviser Robert Costello to Costello's law partner in which Costello wrote that Cohen "continues to slow play us and the president -- is he totally nuts???"

"I am in a golf tournament tomorrow early and again on Sunday. What should I say to this a------ ? He is playing with the most powerful man on the planet," Costello wrote.

"That email certainly speaks for itself, does it not, Mr. Costello?" Hoffiner asked.

"Yes it does," Costello said.

Costello insisted that he was not working to advance Trump's interests and denied the suggestion that he "lost control" of Cohen.

Prosecutors displayed an email from Michael Cohen's then-legal adviser Robert Costello to Costello's law partner Jeffrey Citron from Aug. 8, 2018, in which Costello shared a link to a Fox News story about Rudy Giuliani joining Trump's legal team.

"All the more reason for Cohen to hire me because of my connection to Giuliani, which I mentioned to him in our meeting," he wrote.

In another email, Costello said, "Our issue is to get Cohen on the right page without giving him the appearance that we are following instructions from Giuliani or the President. In my opinion this is the clear correct strategy."

Questioned on the witness stand about that email, Costello told prosecutor Susan Hoffinger that he wanted "to get everybody on the same page because Michael Cohen had been complaining incessantly that Rudy Giuliani was making statements in the press that Michael Cohen didn't approve of."

Costello told Hoffinger he has other emails clarifying that, "which I'd be delighted to tell you."

"That's all right," Hoffinger replied snarkily.

The gallery laughed, prompting a court officer to yell, "Quiet!"

Only a few minutes into prosecutor Susan Hoffinger's cross-examination of Michael Cohen's former legal adviser Robert Costello, their exchanges are already sounding tense.

Hoffinger attempted to confirm that Costello boasted about his relationship with Rudy Giuliani, but Costello denied he did so during his first meeting with Cohen.

"You are quoting from an email that is much later," Costello said.

"I am not quoting from an email," Hoffinger replied.

Hoffinger then asked Costello about his relationship with Giuliani.

"He's been to your wedding?" Hoffinger asked.

"Yes he was," Costello said.

“Let’s get the witness please,” Judge Juan Merchan said after taking the bench.

Michael Cohen's one-time legal adviser Robert Costello entered the courtroom and took the witness stand to continue his cross-examination.

“Good Morning, Mr. Costello. Welcome back,” Judge Merchan said.

The defense made a motion for the dismissal of the case, with defense attorney Todd Blanche telling Judge Merchan, "There's absolutely no evidence the filings were false, the business records were false."

When the invoices for Cohen's payment were sent to the Trump Organization there's no evidence they were entered improperly, Blanche said. "At the start, there is absolutely no false business filings. They're accurate business filings," he said.

Trump looked directly at Blanche as the attorney addressed Merchan.

"There's no evidence that there's any intent to defraud by Mr. Trump in connection to these filings," Blanche argued.

"There are no other crimes," defense attorney Todd Blanche argued about the legal standard in the case -- that Trump falsified business records in furtherance of another crime. "There is no evidence that any one was thinking about a campaign finance charge in 2016 when this payment was made to Ms. Daniels."

"The prosecutors have talked in their opening statement and in papers about some sort of conspiracy to influence the election but as the court knows there has to be something illegal about this effort," Blanche said. "There's no evidence from any of the witnesses who testified of any criminal intent."

"There is no way that the court should let this case go to jury relying on Mr. Cohen's testimony," Blanche said "Without Mr. Cohen, there is no case."

Judge Merchan asked if Blanche was calling for him to rule that Cohen's testimony is "not credible as a matter of law."

"Absolutely, that's exactly what we're calling on the court to do," Blanche replied. "He testified, and he lied under oath -- in this courtroom."
