Prosecutors have arrived in court for today's proceedings. Unlike yesterday, Manhattan DA Alvin Bragg is not currently in the courtroom.

Donald Trump has arrived at the courthouse with members of his entourage.

North Dakota Gov. Doug Burgum and Florida Reps. Byron Donalds and Cory Mills are planning to come with former President Trump to court today, in addition to House Speaker Mike Johnson, according to sources familiar with the matter.

The group is expected to be in court as former Trump attorney Michael Cohen resumes his testimony this morning.

House Speaker Mike Johnson is going to criminal court in New York with former President Trump this morning, a source with direct knowledge confirms to ABC News.

Johnson will commute with Trump in his motorcade from Trump Tower to the lower Manhattan courthouse, and is expected to be in the courtroom for the morning session.

An attorney for Stormy Daniels told CNN that Daniels wore a bulletproof vest to court before her testimony last week.

"She was concerned about the security coming into New York," attorney Clark Brewster said. "She wore a bulletproof vest every day until she got to the courthouse."

Brewster said that Daniels was concerned about a rogue actor targeting her due to her testimony in the trial.

"Before she came on Sunday, I mean she cried herself to sleep," Brewster said. "She was paralyzed with fear."

Daniels testified over two days last week that she and Trump had a sexual encounter in 2006 and that she was subsequently paid $130,000 for her silence prior to the 2016 election. Trump has denied all allegations of a sexual encounter.

After the jury was dismissed for the day, Judge Merchan heard arguments from the two sides on whether the defense should be allowed to call an expert witness to explain to the jury how to interpret nuances in election law, particularly the phrase "for the purpose of influencing an election."

"We don't think this jury here should be evaluating a FICA violation," defense attorney Emil Bove argued.

Prosecutors objected, saying only the judge should inform the jury what the law is.

There is a "general and widely followed prohibition" against having testimony from witnesses about the law, prosecutor Matthew Colangelo argued, adding that Bove's request "flies directly in the face" of an earlier order issued by Merchan.

"The jury has to be provided instructions one way or another ... about how to apply these principles," Bove argued back.

Merchan said he would think about it over the weekend, but told the defense, "Until you hear differently from me, my ruling has not changed" that their requested testimony would not be permitted.
