Unlike courtrooms where the counsel tables are arranged side by side, the counsel tables in the courtroom this morning are arranged behind one another, with Trump and his attorneys seated two tables behind Carroll and her counsel.

Trump appeared to take note of that arrangement when he entered the courtroom.

He appeared to point at Carroll, then he and his team asked a man seated at the table between them to slide over -- possibly to block Trump's view of Carroll, or to provide a better view of the proceedings.

On Friday, Judge Kaplan denied a request from Trump's attorneys to postpone the trial for a week so Trump could attend Thursday's funeral of Amalija Knavs, the mother of former first lady Melania Trump, who died last Tuesday after a long health battle.

In court this morning, Trump attorney Alina Habba repeated her request for an adjournment so Trump can attend Knavs' funeral.

"You asked me for a week's adjournment and I denied it," Judge Kaplan said. "The repetition is not accomplishing anything."

The judge said Friday that he would grant a continuance so the trial, which was initially scheduled to conclude this week, would be extended so Trump could testify on Monday, Jan. 22.

"The court has made a number of rulings precluding evidence and argument," said Judge Lewis Kaplan as court got underway, asking each side's lead attorney to affirm that the parties understood the rules.

The defense objected, arguing that the court lacked jurisdiction. Kaplan quickly dispensed with the objection, saying, "Overruled." Kaplan, who has a reputation as a no-nonsense judge, also overruled several other defense objections.

"I do think these are issues that will become an issue on appeal. We still don't know what witnesses are coming in and which aren't," Trump attorney Alina Habba said, before Kaplan interrupted, saying, "Ms. Habba you have had a witness list for months."

Habba pressed on, with Kaplan noting her objections.

"I have heard you, I have considered what you have to say and I have ruled," Judge Kaplan said.

Donald Trump has taken a seat in court, where jury selection in his defamation trial is scheduled to get underway this morning.

His decision to attend this trial is a clear shift for the former president, whose lawyers portrayed his absence from last year's defamation and battery trial as a service to New York City, saying the city would not have to suffer the "logistical and financial burdens" of Trump's attendance.

Carroll's attorneys, however, pounced on Trump's absence.

"He didn't even bother to show up here in person," attorney Roberta Kaplan told the jury.

Writing on social media last month, Trump blamed his absence at the trial on "not good advice" from his then-lawyer Joe Tacopina.

"I was asked by my lawyer not to attend--'It was beneath me, and they have no case.' That was not good advice," Trump wrote.

Trump attorney Alina Habba is serving as Trump's lead defense attorney for this week's trial.
