The judge overseeing former President Donald Trump’s criminal case in Manhattan fined him $1000 on Monday for another violation of the court’s gag order that bans him from making public comments about the jurors, witnesses, attorneys, court staff and the judge’s family.

Judge Juan Merchan, in issuing the fine, said again that the next punishment for Trump if he violates the gag order again might be imprisonment.

“It appears that the $1,000 fines are not serving as a deterrent. Therefore going forward, this court will have to consider a jail sanction. Defendant is hereby put on notice that if appropriate and warranted, future violations of its lawful orders will be punishable by incarceration,” Merchan wrote in a court order.

According to the judge, Trump violated the gag order in an interview in which he criticized the composition of the jury, saying it was mainly filled with Democrats.

“Defendant violated the Order by making public statements about the jury and how it was selected. In doing so, Defendant not only called into question the integrity, and therefore the legitimacy of these proceedings, but again raised the specter of fear for the safety of the jurors and of their loved ones,” Merchan wrote.

In an interview with Real America’s Voice last month, Trump had said, “You know [the judge is] rushing the trial like crazy. Nobody’s ever seen a thing go like this. That jury was picked so fast — 95% Democrats. The areas mostly all Democrat. You think of it as a — just a purely Democrat area. It’s a very unfair situation, that I can tell you.”

The comment about the jury composition was the only comment Merchan determined was a violation of Trump’s gag order amongst several comments prosecutors flagged as a potential violation.

This fine comes after Trump was fined $9000 last week for making social media posts which the judge determined were a violation of the gag order.

Trump, who has consistently slammed the case against him as a political warfare, said outside the courtroom on Monday morning that the judge had taken away his constitutional rights.

“It’s a ridiculous case. I did nothing wrong. Absolutely nothing wrong. He’s taken away my constitutional right to speak. I was in Miami this weekend, and reporters are asking me questions, the same questions like you are asking me, and I have to say I have a gag order, I can’t speak about it. Never happened before ever,” he said.
