What happens to the Trump Georgia 2020 election case if Fani Willis is disqualified by court?

The judge overseeing the sprawling case against former President Donald Trump and his co-defendants in Georgia's election interference probe is expected to decide by Friday whether he'll disqualify Fulton County District Attorney Fani Willis and her office from prosecuting the case. If he does, what would happen next?

In mid-February, Fulton County Judge Scott McAfee heard hours of fiery testimony about the romantic relationship between Willis and the special prosecutor she hired for the case, Nathan Wade. There were arguments from both sides about the timeline of the relationship as well as whether the relationship was "improper" and amounts to a conflict of interest.

Willis and Wade have admitted to the relationship, which they say ended last summer, but both argued there is no conflict of interest.
