One interlude from the aftermath of the 2020 election demonstrates how Moss' career prospects deteriorated, she testified.

Moss said she felt so disillusioned with election work by mid-2021 that she sought work elsewhere. She applied for a job at a Chick-fil-A restaurant and secured an interview.

"I was dressed up. I had my notebook with my resume. I was excited, I was ready," Moss said. The interview "went great," she said, even though she realized that, without relevant experience, she would be asked to do menial tasks.

"I had made up my mind that, oh well, I'll have to start at the bottom," she testified. "And if I can work my way up at [voter] registration, I can work my way up here."

Before leaving, however, the interviewer showed her an article on his laptop and said, "Tell me about this. Is this you? Is this true?"

The article featured an image of her face with the word "Fraud" plastered across it.

"The more he was talking, the more I just tuned it out," Moss said. "I was so shocked, I was so embarrassed … I just had to leave. I just left."

Shaye Moss felt dejected and fearful after Rudy Giuliani's defamatory statements and accusations about her proliferated online -- prompting the veteran election worker to change her appearance and leave her job.

John Langford, an attorney for Moss, displayed emails and messages she received on social media in late 2020, as her name circulated online in right-wing media. One read, "Be glad it's 2020 and not 1920."

The chilling message, which she said made her "afraid for my life," prompted her to assume a new physical identity.

"I went into my hair salon and I asked my stylist to make it so the same person she saw walk in here is not the person who leaves," Moss recalled.

Her stylist, she said, "dyed it a strawberry blond color." A selfie Moss took the following day showed her with a "puffy face from crying all night."

Though her hair changed, Moss said she returned to work after "the worst Christmas" of her life, determined to return to normalcy. "My goal was still to make sure that everything was ready for our next election, that everything ran smoothly," she testified.

Instead, she recalled, "Things ain't never returned to normal."

Moss left the Fulton County elections office in April 2022 after she was passed over for a promotion. "It felt like a slap in the face," she said, because she sensed that her superiors thought it would look bad for the county.

"I wanted to retire a county worker, like my grandma -- make her proud, make my mom proud -- but..." she said, trailing off in tears.

Rudy Giuliani, seated at the defense table, showed little emotion as Moss wept on the witness stand. Leaning with his elbow on the table, the former mayor took intermittent notes as she testified.

A visibly upset Shaye Moss described what happened on Dec. 4, 2020 -- the day her boss informed her about the deluge of "nasty, hateful, violent" messages directed at her from online users accusing her of election fraud.

Moss said when her supervisor summoned her to his office, she thought she might be in line for a promotion. Colleagues smiled and gave her a thumbs up as she waded through their cubicles, she recalled.

Instead, Moss testified, she was shown social media posts accusing her of manipulating ballots.

"I am shown these videos, these lies, everything that's been going on that I had no clue about," Moss recalled. "I was confused, I was immediately fearful."

After returning to her desk, Moss said she "couldn't concentrate" for the rest of the day.

Taking the witness stand, Shaye Moss described the pride she felt as an election supervisor in Fulton County -- the position she held on Election Day in 2020.

Moss began her career in elections in 2012 as a temporary worker in the Fulton County elections office mail room. Five years later, she said she secured a promotion to permanent work.

"I worked really hard for that position. I was so excited I literally dropped to my knees and cried," Moss said. "It was like winning the golden ticket with Willy Wonka. I was so proud of myself."

Moss said she felt proud to work in elections and took particular delight in helping the elderly and others who found it difficult to cast their ballots. She said her grandmother inspired her to pursue a career in elections.

"No, I did not like my job -- because I loved my job," Moss recalled. "It would make my grandmother proud … my grandmother enjoyed telling her friends … that her grandbaby runs the election."

When Rudy Giuliani accused Ruby Freeman of "surreptitiously" passing her daughter a USB drive while the two were counting ballots on Election Day at State Farm Arena -- a central tenet of his false claims about the two women -- what he actually saw, according to Freeman, was something far less sinister: a ginger mint.

As Freeman took the stand, her attorney entered a ginger mint into evidence -- and Freeman passed the judge a ginger mint, too.

"I'm going to use this," Judge Beryl Howell said.

Freeman explained that she always has the candies with her. She passes them out to clients of her clothing boutique and those in need.

"I felt that it was healthy," she testified.

Freeman, who always went by "Lady Ruby," said she can no longer use her nickname publicly or in business.

"I can't use my name anymore, so I'm not Lady Ruby," she said as her voice cracked. "Sometimes I don't know who I am."
