The prosecution objected to the defense calling Robert Costello, Michael Cohen's former attorney to the stand.

Out of earshot of the jury, prosecutor Susan Hoffinger asked Judge Merchan to omit Costello or limit his testimony to two questions.

"I think there's very limited testimony that's permissible here if at all," Hoffinger said.

The defense said it wants to use Costello to rebut Cohen's testimony about a "pressure campaign" carried out against him not to flip on Trump after Cohen made Stormy Daniels payment.

Costello, a longtime Trump ally, testified before the grand jury in March 2023 as an exculpatory witness at the request of Trump's attorneys.

On cross-examination, prosecutor Becky Mangold quizzed defense witness Daniel Sitko about the technical process for putting together the summary chart from cell phone records.

The defense attempted to show through the call summary that Cohen and his then-attorney Robert Costello spoke 75 times. On cross-examination, the defense paralegal conceded it wasn't quite that many.

After Sitko stepped off the witness stand, the defense called Robert Costello himself.

The defense called Daniel Sitko, a paralegal for defense attorney Todd Blanche.

Sitko introduced a summary chart of phone calls between Michael Cohen, his one-time attorney Robert Costello, and the law firm of Davidoff Hutcher & Citron.

Defense attorney Todd Blanche, on redirect examination, asked Michael Cohen about the photograph of Trump and bodyguard Keith Schiller together on Oct. 24, 2016, at 7:57 p.m.

"Your testimony is still, just so I understand, is in that 90 seconds you spoke to Mr. Schiller about the problem you were having with the 14-year-old, got him to agree to take care of it," and also had time to talk to speak about Daniels to Trump.

Cohen stood by his testimony.

Cohen also testified again that his $420,000 payment in 2017 was a reimbursement, not a payment for legal services.

"It was a reimbursement -- it wasn't a payment for your services?" Blanche asked.

"Correct," Cohen said.

Blanche attempted to cast doubt on that claim by highlighting Trump's frugality.

"Did he overpay for things regularly?" Blanche asked.

"No, sir," Cohen said.

Cohen then concluded his testimony and the state rested its case.

"Your honor, the People rest," Steinglass said.

Last week, Michael Cohen testified that he did not trust Robert Costello to be his lawyer because he worried any information shared with him would get to Rudy Giuliani and then get to Trump.

But Cohen testified today that he took advantage of that back channel -- including asking Costello to ask Giuliani to try to learn more about the origins of the federal investigation that led to the search of Cohen's office and hotel room.

“I spoke with the person you asked me to and he said he would find out exactly how the matter ended up in the SDNY and in particular who in Main Justice approved this,” Costello wrote in an email to Cohen on April 23, 2018.

Cohen confirmed the “person” mentioned above was Rudy Giuliani.
