When Rudy Giuliani entered the courtroom some 20 minutes late due to delays with the courthouse security line, it was the first time he shared a room with Ruby Freeman and Shaye Moss.

Freeman and Moss kept their backs turned away from Giuliani as he entered the courtroom. Moss appeared to swivel her chair slightly to avoid facing him directly.

Giuliani took a seat at the defendant's table alongside his attorney, Joseph Sibley.

While waiting for Giuliani, Sibley had asked Judge Howell's permission for Giuliani to bypass the security line moving forward. She said she would discuss it with court personnel, but laid the blame at Giuliani's feet for his arriving "tardily."

Judge Howell has begun reading instructions to dozens of prospective jurors, after proceedings were delayed slightly due to Giuliani's late arrival and some apparent issues with juror paperwork.

Howell rose and swore in jurors before the selection process got underway. She emphasized that she would endeavor to seat an impartial and unbiased jury.

"The court has already determined that Mr. Giuliani is liable for defamation, and that Ms. Freeman and Ms. Moss are entitled to receive compensation, including in the form of punitive damages, for Mr. Giuliani's willful conduct," Howell told jurors.

"The only issue remaining in this trial is for the jury to determine any amount of damages Mr. Giuliani owes to plaintiffs for the damage caused by his conduct," Howell said.

The $15.5 million to $43 million that Freeman and Moss are seeking from Giuliani reflects the emotional distress and monetary losses associated with the former mayor's defamatory comments, according to attorneys for the mother and daughter.

If the plaintiffs receive anywhere near those figures, it would mark the latest financial blow to a man who once raked in tens of millions of dollars through security consulting and speaking fees.

Judge Beryl Howell has already ordered Giuliani to pay Freeman and Moss upwards of $230,000 as a sanction for failing to comply with the discovery process of sharing information relevant to the case. In court filings over the summer, Giuliani's lawyer asked the judge if Giuliani could defer payment, citing the former mayor's "financial difficulties" as a result of fighting a slew of litigation elsewhere.

Giuliani stands to owe millions more if he loses cases brought by two voting machine companies and his own longtime personal attorney, among other legal challenges he faces. Giuliani has denied all claims.

Jury selection in the case gets underway at the D.C. federal courthouse this morning, where eight Washington residents will be chosen to serve.

Jurors will be tasked with attaching a monetary value to the harm caused by the defamatory statements a judge found Rudy Giuliani liable for making in the wake of the 2020 presidential election.

When the parties arrive in court this morning, it will be the first time Ruby Freeman and Shaye Moss face Giuliani in person.

Speaking to reporters outside court, Rudy Giuliani said he didn't have "an opportunity to present evidence" and that he plans to appeal the decision.

"Obviously we will move for a new trial, we will certainly appeal," Giuliani said.

When asked by reporters why he didn't testify, Giuliani said he believed the judge was threatening him with contempt.

"I didn't testify because the judge made it clear that if I made any mistake or did anything wrong, she was considering contempt," Giuliani said.

"I have no doubt that my comments were made and they were supportable and supportable today. I just did not have an opportunity to present the evidence that we offered," he said.

Judge Beryl Howell on Tuesday admonished Giuliani for making "additional defamatory comments" about Ruby Freeman and Shaye Moss late Monday when he told ABC News' Terry Moran that he stands by his statements that the two women "were engaged in changing votes."

Those comments "could support another defamation claim," Howell told Giuliani, who subsequently elected not to testify in the case.
