Following the defense resting its case, Judge Juan Merchan told the parties that "summations will not be quick" and that they "will take at least a day." Jury instructions will then take at least an hour, he said.

"At the end of the day, I think the best thing we can do is to adjourn now until next Tuesday. At that time you will hear summations from the attorneys," Merchan said.

Merchan says that deliberations could begin as early as next Wednesday.

Merchan told the jury he opted to delay the summations because of this week's abbreviated schedule and his belief that "it's always ideal or best not to break up summations."

Trump's eyes were closed, his head titled back, as Merchan instructed the jury to return on Tuesday.

The jury then left the courtroom.

"You still have a lot of animosity against Michael Cohen," prosecutor Susan Cohen Hoffinger asked Michael Cohen's then-legal adviser Robert Costello after displaying emails from 2018.

"I don't have animosity but --," Costello replied before being cut off.

"Yes or no," Hoffinger said.

Hoffinger then asked Costello bluntly if he was trying to "intimidate" Cohen regarding his 2018 congressional testimony.

"Intimidate Michael Cohen?" Costello asked incredulously.

"Yes, that's my question," Hoffinger repeated firmly.

"Ridiculous, no," Costello responded.

Hoffinger then concluded her cross examination, which was followed by a brief redirect.

"Your honor, the defense rests," the defense team told Judge Merchan.

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.
