After approximately five weeks, 19 witnesses, reams of documents and a dash of salacious testimony, the prosecution against Donald Trump rested its case Monday, handing over to the defense before closing arguments expected next week.

Trump’s team immediately sought to undermine key testimony against the former president, who is accused of covering up hush money paid to a porn star over an alleged encounter that could have derailed his successful 2016 White House bid.

His attorneys called lawyer Robert Costello — who once advised star prosecution witness Michael Cohen before falling out with him — in an apparent attempt to puncture Cohen’s credibility.

But Costello’s start on the stand was shaky at best, as his dismissive tone provoked an angry response from Judge Juan Merchan.

Merchan chided Costello for remarking “jeez” when he was cut off by a sustained objection and, at another point, “strike it.” Merchan told him: “I’m the only one that can strike testimony in the courtroom. Do you understand that?”

"And then if you don’t like my ruling, you don’t give me side eye and you don’t roll your eyes.”

Merchan was about to bring the jury back in when he asked Costello, “Are you staring me down right now?” and then kicked out the press to further admonish him.

"I’m putting you on notice that your conduct is contemptuous,” Merchan said, according to the transcript of the conversation that occurred when the press was out of the room. ”If you try to stare me down one more time, I will remove you from the stand.”

Costello didn’t return a message seeking comment Monday night.

Trump, speaking to reporters afterward, called the episode “an incredible display,” branding the proceedings “a show trial” and the judge “a tyrant.”

Extended quibbling among the two legal teams, along with the upcoming holiday weekend, means closing arguments that the judge had hoped could start Tuesday are now anticipated for next week.

It’s unlikely and risky, but the door remains open for Trump to take the stand in the criminal trial, the first ever of a former US president.

Experts doubt he will, as it would expose him to unnecessary legal jeopardy and forensic cross-examination by prosecutors — but his lawyer Todd Blanche has raised the prospect.

On Monday, Blanche finished his third day of questioning Cohen after hours of at times digressive, at other times bruising, exchanges.
