Terrance Bradley, a former law partner of Nathan Wade, is declining to answer questions about Fani Willis and Wade's relationship, citing attorney-client privilege.

"I was advised by the bar … I cannot reveal anything that I saw or learned," Bradley said. "I am here because I also have a law license and I'm not trying to lose that."

The judge pushed back, saying, "That's a broader representation of attorney-client privilege than I've ever heard."

The debate has drawn the first comments from Donald Trump's attorney Steve Sadow, who said of Bradley's view of attorney-client privilege, "There is no such case law."

Sadow even suggested Bradley be held in contempt if he continues to refuse to answer questions.

Michael Roman's attorney Ashleigh Merchant called her first witness in the effort to disqualify DA Fani Willis -- a former DA office employee named Robin Yeartie, who Merchant says has firsthand knowledge that Wade and Willis’ relationship began before he was hired, in contradiction to Wade’s sworn affidavit -- but Yeartie is not in court yet.

As a result, a new first witness has taken the stand: Terrence Bradley, a former business associate of prosecutor Nathan Wade who represented him in his divorce case.

"It wasn't my choice," Bradley said of having to testify today.

The state has objected to Bradley's testimony, saying it is protected by attorney-client privilege. But Roman's team says the information is not related to his representation of Wade in the divorce matter.

The evidentiary hearing is underway in front of a packed courtroom.

DA Fani Willis has not yet entered the courtroom, but special prosecutor Nathan Wade is present, along with multiple attorneys for defendants in the DA's election interference case, including Trump attorney Steve Sadow and Mike Roman's attorney Ashleigh Merchant.

Two of Trump's co-defendants in the case, Harrison Floyd and David Shaffer, are also in attendance.

Former President Trump's attorney has arrived for the Fulton County proceedings, but his client won't be attending the hearing.

Instead, Trump is attending a hearing in his criminal hush money case in New York.

The former president is not required to be at either of the two hearings taking place today.

Trump attorney Steve Sadow accused prosecutor Nathan Wade of perjury on the witness stand, related to when his relationship began with DA Fani Willis.

"Mr. Wade committed perjury on the witness stand," Sadow said standing in court, continuing his argument for why Terrence Bradley's testimony regarding his texts and knowledge of Wade and Fani Willis' relationship.

Bradley has testified that he did not have personal knowledge of the relationship between Wade and Willis. But the defense is arguing the texts would show otherwise.

"A lawyer shall not knowingly failed to disclose and material fact to a tribunal. When disclosure is necessary to avoid assisting a criminal or fraudulent act," Sadow said.
