In closing arguments, plaintiffs' attorney Michael Gottlieb used Rudy Giuliani's own words against him, playing video of the former mayor's exchange with ABC News' Terry Moran outside of court on Monday.

Giuliani told Moran, "Everything I said about them is true" and that the women "were engaged in changing votes," referring to Ruby Freeman and Shaye Moss.

"That is a fiction," Gottlieb told jurors. "And it ends today."

Gottlieb also cited a passage from Giuliani's best-selling book, "Leadership," in which Giuliani said his father instructed him from a young age not to bully or attack vulnerable people.

"Those are wise words," said Gottlieb. "If only Mr. Giuliani had listened."

When jurors entered the courtroom, Trump attorney Joseph Sibley rested his case without presenting any witnesses or entering any records into evidence.

An attorney for Freeman and Moss then began his closing argument.

Judge Howell criticized key arguments presented at trial by Rudy Giuliani's attorney before jurors entered the courtroom this morning, reiterating her prior rulings that the former mayor's rhetoric about Ruby Freeman and Shaye Moss was "totally false."

Howell was responding to a last-ditch effort by Giuliani attorney Joseph Sibley to seek a ruling that plaintiffs had failed to meet the burden of proving their case, known as a Rule 50 motion.

Howell denied that motion, and in the process took aim at arguments core to Sibley's case -- as well as comments Giuliani had made outside of court.

"The powerful testimony of these Georgia officials demonstrated again and again and again" that those allegations were "totally false," Howell said of earlier testimony from two Georgia investigators that there was no evidence of election fraud.

Freeman and Moss organized "no highfalutin strategy like the one Giuliani" coordinated on behalf of former President Donald Trump, the judge added.

Howell took particular issue with Sibley's attempt to claim that no amount of money could change the mind of those who believe the 2020 election was stolen from Trump. Sibley compared them to "flat-Earthers," who believe, despite overwhelming evidence to the contrary, that the Earth is flat.

Prior to the unexpected announcement this morning that Rudy Giuliani will not testify in his own defense, the former mayor had repeatedly told reporters that he looked forward to presenting his side of the story at trial.

"When I testify, the whole story will be definitively clear that what I said was true, and that, whatever happened to them, which is unfortunate about other people overreacting -- everything I said about them is true," Giuliani told ABC News' Terry Moran on Monday.

When court reconvened the following morning, on Tuesday, a visibly frustrated Judge Beryl Howell admonished Giuliani, suggesting his remarks "could support another defamation claim."

She reiterated the court's prior ruling that Giuliani's allegations against Freeman and Moss were untrue and cautioned him against raising arguments that she has already ruled on.

Departing court after the first day of the trial, Rudy Giuliani told ABC News' Terry Moran that he has no regrets about his treatment of Ruby Freeman and Shaye Moss -- and he doubled down on his core allegations about them.

"When I testify, the whole story will be definitively clear that what I said was true, and that, whatever happened to them -- which is unfortunate about other people overreacting -- everything I said about them is true," Giuliani told reporters.

"Do you regret what you did to Ruby and Shaye?" Moran asked.

"Of course I don't regret it," Giuliani said. "I told the truth. They were engaged in changing votes."

"There's no proof of that," Moran responded.

"You're damn right there is," Giuliani retorted. "Stay tuned."

Court will resume Tuesday at 9 a.m. ET.
