Judge Juan Merchan has restarted court for the afternoon proceedings following the lunch break.

Both Donald Trump and Manhattan District Attorney Alvin Bragg are in attendance.

Trump made no remarks to reporters before entering the courtroom after the break.

Trump attorney Todd Blanche, responding to prosecutors' request for Judge Merchan to fine Trump for three social media posts they say violated the judge's limited gag order, characterized the posts as "limited responses to this barrage of attacks" against him by Stormy Daniels and Trump's former attorney Michael Cohen.

"It's not as if President Trump is going out and targeting individuals. He's responding to … attacks from these witnesses," Blanche said.

The three posts by Trump -- two on April 10 and a third on April 13 -- came just days before the trial.

In one of those posts, Trump thanked Daniels' former attorney, Michael Avenatti for "revealing the truth about two sleaze bags" -- a statement prosecutors say clearly "attacks" Daniels and Cohen and their participation in the trial.

Judge Merchan said Blanche would have an opportunity to respond in a paper filing.

"I'll take this upstairs with me over the lunch recess," Merchan said.

The judge then recessed court until 1:30 p.m. ET.

Prosecutors with the Manhattan district attorney's office asked Judge Merchan's permission to seek to hold former President Trump in contempt for alleged violations of the judge's order against attacking witnesses.

"We're seeking permission to file a proposed order to show cause to show why the defendant should not be held in contempt based on extrajudicial statements," assistant district attorney Chris Conroy said.

He said the order would seek a $1,000 fine for each of three social media posts that prosecutors said violated the judge's limited gag order.

The three allegedly offending posts occurred this month when Trump reposted a social media post from Stormy Daniels' former attorney Michael Avenatti that was disparaging of Daniels and former Trump attorney Michael Cohen, plus a second post about Daniels and a third post about a member of the prosecution team.

"It is important for the court to remind President Trump he is a criminal defendant," Conroy said. "The defendant has expressed a willingness to flout the order" Merchan imposed.

Defense attorney Todd Blanche said the three posts do not violate the gag order. He sought permission to formally respond in writing.

Former President Donald Trump "wants to be present at everything" during trial, his attorney told the court, including side conferences during the jury selection process.

Judge Merchan suggested that could create "logistical" issues, citing the the presence of Secret Service agents, but suggested he would do his best to accommodate Trump.

The judge then directed a series of questions to Trump himself, asking him whether he understands that his failure to attend the trial or appear for sentencing could merit penalties from the court.

After each question, Trump nodded his head and appeared to answer verbally, "Yes," or "I do."

Former National Enquirer publisher David Pecker, back on the witness stand, pointed at Donald Trump and flashed a smile when he was asked to identify the defendant. Trump turned his chin up and grinned at his longtime friend.

"I met Mr. Trump at Mar-a-Lago," Pecker said. "I've had a great relationship with Mr. Trump over the years."

That relationship started in 1989 when Pecker wanted to start a magazine called Trump Style.

"He was very helpful in introducing me to other executives in New York. He would always advise me of parties or events that I would go to," Pecker said, adding that Trump was among the first to congratulate him upon acquiring the National Enquirer.

Pecker described how Trump became a "major celebrity" after launching The Apprentice and later Celebrity Apprentice, and how the National Enquirer was there to juice Trump's profile.

"He was always kind enough to send me the content showing the ratings and I was able to publish that," Pecker said of their "great mutual beneficially relationship.

Pecker said he considered Trump a friend from 2015 to 2017, calling him by the familiar "Donald," as he pursued the White House for the first time.

"After he announced his run for the presidency I saw Mr. Trump more frequently, maybe once a month," Pecker said. The two spoke "maybe once every couple of weeks."

Pecker recalled meeting Trump in his office when his assistant brought a batch of invoices and checks to sign.

"As I recollect the entire package was stapled together," Pecker said.

"So you observed him reviewing an invoice and signing a check?" prosecutor Josh Steinglass asked. "That's correct," Pecker responded.

"I would describe him as very knowledgeable, very detail-oriented, almost as a micromanager," Pecker said.

When Steinglass asked how Trump was with money, Pecker responded, "He was very cautious and very frugal."
