Prosecutors for the Manhattan district attorney’s office have entered the courtroom.

Manhattan District Attorney Alvin Bragg is not currently in attendance.

Former President Trump has arrived at the courthouse for today's proceedings.

This will be the final day of court this week, as court is off on Friday for Trump to attend his son Barron's high school graduation.

Michael Cohen has arrived at the lower Manhattan courthouse for his testimony this morning.

Proceedings are scheduled to get underway at 9:30 a.m. ET.

Testimony is scheduled to conclude at 4 p.m., after which Judge Juan Merchan is scheduled to hear arguments from the parties about the bounds of potential testimony from a defense expert witness.

Michael Cohen returns to the witness stand this morning, where the former Trump attorney is expected to face a full day of cross-examination.

Cohen, under direct examination earlier this week, described in-person meetings and phone calls with Donald Trump, who he said joined into an agreement with tabloid publisher David Pecker to catch and kill negative stories ahead of the 2016 election; approved a $130,000 hush money payment from Cohen to Stormy Daniels; and signed off on an arrangement to reimburse Cohen in 2017 using what prosecutors say were falsified invoices. Trump has denied all wrongdoing.

Defense attorneys are expected to question Cohen's credibility based on his past testimony and previous statements he has made in interviews, podcast and books.

Michael Cohen, who for nearly a decade was Donald Trump's trusted adviser, personal attorney, and self-described "attack dog with a law license," is scheduled to take the stand this morning as the prosecution's star witness in Trump's criminal hush money trial.

According to prosecutors, Cohen was in the room in when Trump and former National Enquirer publisher David Pecker agreed to a catch-and-kill scheme to hide negative information about Trump from 2016 voters, and Cohen himself made a $130,000 payment to Stormy Daniels to buy her silence about an alleged 2006 sexual encounter with Trump. The former president, who has denied the encounter took place, is on trial for allegedly falsifying business records related to his company's reimbursement to Cohen in 2017.

But Cohen's value to the prosecution's case could be endangered by the disbarred lawyer's credibility issues. Cohen pleaded guilty in 2018 to tax evasion, campaign finance allegations, and lying to Congress in what Cohen says was an effort to protect Trump. The former president's lawyers have also argued that Cohen perjured himself again when he testified at Trump's civil fraud trial last year, and accuse Cohen of making his livelihood off books and podcasts that antagonize Trump.

Cohen is the final key witness in the prosecution's case, after which the defense will present its case.
