Judge Juan Merchan began the day's proceedings by clearing up a "misunderstanding" about the case's limited gag order's impact on Trump's ability to testify.

It comes after Trump, speaking after court yesterday, told reporters, "I'm not allowed to testify because this judge who's totally conflicted has put me under an unconstitutional gag order," referring to the limited gag order that keeps him from directing prohibited comments at witnesses, jury members, and attorneys in the case.

"I want to stress, Mr. Trump, that you have an absolute right to testify at trial," Merchan said from the bench while looking directly at the former president. "That is a constitutional right that cannot be denied ... it is a fundamental right that cannot be infringed upon."

"The order on extrajudicial statements does not prevent you from testifying in any way, it does not prohibit you from taking the stand and it does not prohibit or minimize what you could say from the witness stand," Merchan said.

The judge told Trump and his lawyers that the order only prohibits extrajudicial statements -- not statements made during the actual proceeding.

"It does not apply to statements made from the witness stand," Merchan said, directing Trump to speak to his lawyers if he has any further questions.

Trump clearly nodded along as Merchan spoke to him.

Donald Trump has entered the courtroom for the day's proceedings.

The former president was accompanied by his usual entourage of lawyers, Secret Service agents and campaign staffers.

A custodial witness who testified yesterday about the contents of former Trump attorney Michael Cohen's phone is scheduled to return to the witness stand this morning on Day 11 of the trial.

Douglas Daus, who handles the processing of electronic devices for the Manhattan district attorney's office, told jurors what he found when he extracted the contents of Cohen's two iPhones -- including a September 2016 recording of Donald Trump discussing the arranged purchase of Karen McDougal's story that was made public in 2018.

Daus also testified that Cohen had nearly 40,000 contacts on one of this phones, including 10 pages of contact information s for Trump alone.

Speaking to reporters outside the courtroom, former President Trump signaled that he might not be taking the stand in the trial in response to a question about what he thought of Keith Davidson's testimony.

"I'm not allowed to testify because this judge who's totally conflicted has put me under an unconstitutional gag order. Nobody's ever had that before," Trump said, despite the limited gag order only keeping him from directing prohibited comments at witnesses, jury members, and attorneys in the case.

"The easiest question so far," Trump told reporters, "but I'm not allowed to testify because this judge is totally conflicted, has me under an unconstitutional gag order."

Longtime Trump aide Hope Hicks said that she exchanged a series of text messages with Michael Cohen after the November 2016 Wall Street Journal story on the Karen McDougal agreement was published.

"Michael asked me to call him, Michael asked me for updates," Hicks said.

"'Lots of innuendos with little fact,'" Cohen wrote to Hicks the night the story was published. "'Poorly written and I doubt see it getting much play." Hicks said "doubt" was a typo and it should have read "don't."

In ensuing text messages, Cohen and Hicks said they had not noticed substantial interest in other media outlets.

"I told him to 'keep praying,' because this was obviously the only reason why there were six stories," Hicks said with a laugh.
