Sparks flew in a Fulton County, Georgia, courtroom Thursday afternoon as embattled Fulton County District Attorney Fani Willis took the stand to testify against accusations that she had an “inappropriate” affair. with special counsel Nathan Wade, which could derail his case against former President Trump.

At one point, a Trump lawyer, Ashley Merchant, asked Willis in a heated moment if he had any “proof” that he reimbursed Wade for the vacation because the payments were in cash.

“The testimony of one witness is sufficient to prove a fact,” Willis responded. “Are you telling me I’m lying?”

“I ask you if you have any evidence,” the lawyer responded. And Willis replied: “The proof is what I just said.”

“Has Nathan Wade ever visited you at the place where you laid your head?” Merchant asked Willis another question related to the timeline of her relationship with Wade.

“When?” responded an exasperated Willis.

“Has he ever visited you in the place where you lay your head?” the lawyer repeated.

“So let’s be clear why you lied,” Willis said before picking up several stacks of papers.

“Right here, you lied right here,” Willis said, before yelling “No, no, no” when the lawyer intervened.

“It’s a lie,” Willis said as he held two stacks of papers over his head. “It’s a lie.”

At that point a five-minute recess was called.

The situation became so heated that at one point the judge issued a warning to Willis.

He never came there, it’s okay. So if you don’t come somewhere, you can’t live there too,” Willis said, prompting a response from Judge Scott McAfee.

“I’ll have to warn this,” McAfee said. “Listen to the questions as they are asked. If this happens again and again, I will have no choice but to quash his testimony.”

Willis took issue with being characterized as a hostile witness at another time.

“I really want to be here, so I’m not a hostile witness,” Willis said. “I really want to be here.”

“It’s not so much that you are a hostile witness, Ms. Willis. You would be an adverse witness,” McAfee responded. “His interests are opposed to those of Mrs. Merchant.”

“Mrs. Merchant’s interests are, contrary to democracy, your honor, not mine,” Willis responded.

“I had some contact with Mr. Wade in 2021, one of the reasons his allegations are so absurd, or Ms. Merchant’s,” Willis said for another moment before being interrupted by Trump attorney Steve Sadow and ask a question a second time about the timing of a meeting with Wade.

“I had very limited contact with him because Mr. Wade had a form of cancer that makes his accusation somewhat ridiculous,” Willis said.

“I appreciate the characterization,” Sadow said.

“I’m not going to castrate a black man,” Willis responded. “Did you understand that? I don’t think we should argue anymore.”

“You’re confused,” Willis said at another point in the trial. “You think I’m on trial? These people are on trial for trying to steal an election in 2020. I’m not on trial, no matter how much they try to put me on trial.”

Willis hired Wade in 2021 to help prosecute his wide-ranging racketeering case against Trump. Trump’s co-defendant, Michael Roman, alleged in court filings last month that Willis should be disqualified from the case, alleging that she benefited financially from hiring Wade because of her personal relationship.

Wade took the stand at the beginning of the hearing. Craig Gillen, an attorney for Trump’s co-defendant David Shafer, who also asked the court to disqualify Willis, previously questioned Wade about payments Willis made to him for vacations that were made in cash.

The defense is trying to prove the existence and extent of any financial benefit to Willis by Wade from their relationship, which is the crux of their argument that Willis should be disqualified.

Wade said he “does not remember” traveling with Willis in 2021, when he was hired by the district attorney’s office, but he does remember traveling with her in 2022 and 2023. He testified that his relationship with Willis began in March 2022, and Their trips together began in 2022.

Wade testified that Willis gave him back half of the rideshares.

Wade also testified that Fulton County did not pay him as much as the defense claims.. Specifically in 2022, Fulton County paid approximately $300,000 to his law firm. But Wade said he received about $100,000 because the payments were split among three people who worked at the company, all of whom had contracts with the Fulton County prosecutor’s office for various reasons.

Wade’s testimony contradicts earlier explosive revelations from a former “good friend” of District Attorney Willis, who testified Thursday that she has “no doubt” that Willis and Wade had a “romantic” relationship beginning in 2019, contradicting Willis’s previous statements to the court.

The court adjourned around 5 p.m. Thursday and Willis is expected to return to continue testifying on Friday.
