Defense attorney Emil Bove argued that Judge Merchan should tell the jury it must find Trump acted willfully in order to convict.

The district attorney's office argued the jury must find Trump acted unlawfully, not necessarily criminally.

Judge Merchan said he would reserve his decision about whether to include "willful" in the jury charge

Trump was alert and attentive at the start of this afternoon's session, whispering to his attorney Todd Blanche. Now his eyes are closed.

Judge Merchan, ticking through each of the proposed edits to the jury instructions, appears to be focused on making sure the instructions are clear and understandable for the jury.

"We want to make it as easy as possible for the jury," he said.

Judge Merchan declined to add a sentence to the jury charge that there was no limit on Trump's personal contributions to his political campaign in 2015 and 2016.

Defense attorney Emil Bove argued that the line would have told the jury that Trump “could have paid this out of his personal expenses without issue.”

But prosecutors argued that the line was “extraneous” because Trump made the Stormy Daniels payment reimbursement from the Trump Organization, not out of his personal funds.

“It has nothing to do with the case,” Colangelo said.

Defense attorney Emil Bove began the conference by arguing for a jury instruction describing the alleged conspiracy as civil, not criminal.

According to Bove, prosecutors have failed to show that the alleged conspiracy had a criminal object.

“It’s only a crime if it has a criminal object,” Bove said. "To be a criminal conspiracy, there must be a criminal object.”

Judge Merchan is back on the bench, and the parties -- including Trump -- are seated at the counsel tables for the pre-charge conference that will help determine the jury instructions.

Trump, seated next to attorney Susan Necheles, has a pile of papers in front of him.

A day after Judge Judge Juan Merchan threatened to remove him from the witness stand, former federal prosecutor Robert Costello will resume his testimony this morning as the second witness in Donald Trump's defense case.

Costello is expected to be the final defense witness before Trump's lawyers rest their case today.

Yesterday, Costello told jurors about his meetings and phone calls with Michael Cohen in 2018 after FBI agents raided his office and hotel room. Costello advised Cohen and helped pass messages to the Trump, according to Cohen, but never formally represented him as his lawyer.

"Michael Cohen said, numerous times, that President Trump knew nothing about those payments, that he did this on his own, and he repeated that numerous times," Costello testified about the hush money payment to adult film actress Stormy Daniels that sits at the center of the case.

Cohen told the jury that he lied to Costello about Trump's involvement in the scheme to use hush-money payments to hide information from voters.

Costello's reactions to Judge Merchan after taking the stand yesterday afternoon -- responding "jeez" to a sustained objection, rolling his eyes at the judge, and appearing to staring him down -- prompted Merchan to clear the courtroom before threatening to remove Costello from the witness stand.

While defense lawyers suggested yesterday that they would not call Trump to the witness stand, they will likely have to confirm a final decision about the defendant's testimony -- or lack thereof -- before they rest their case.

Judge Merchan has scheduled a charge conference at 2:15 p.m. ET to hear arguments over how to instruct the jury about the law in the case.
