What is the state trying to prove or defend? I’m trying to figure out the players and their objectives here.
The State doesn’t want Bradley to say anything that would contradict Willis or Wade’s testimony and he is trying as hard as possible not to do so.
She has a copy of their text messages they were made at a time before he realized they would end up in Court. Bradley is trying not to admit he told her anything.
My understanding is that this is an evidentiary hearing in which the defense (for the Trump side) is gathering testimonial evidence from witnesses to establish that, either or both, a crime was committed by Fani (and Wade) and/or Fani's romantic involvement with Wade had a prejudicial effect on the case against Trump.
At this point, it looks like Ashleigh Merchant and team are trying to establish, at the least, that the relationship between Fani and Wade started before Wade was hired by the DA's office. Ancillary to that, I think that Merchant et al. are trying to establish that the behavior of Fani and Wade was a financial abuse of the DA's office and Fulton County (trips paid for by Wade for himself and Fani were a form of graft--Fani overpaid Wade and he return the favor with gifts).
As to the question of gifts by vacations, it has been established that Wade paid for all the vacations with a credit card and Fani (it is claimed) reimbursed Wade with cash without any paper trail such as withdrawals of cash by Fani, deposits of cash by Wade, or receipt for such reimbursement (given by Wade to Fani showing amount and reason for an exchange of cash).
As an aside, the DA's office requires Fani to report any gifts and it would appear to be incumbent upon Fani to have a receipt from Wade for her reimbursements for vacations so that she can prove such vacations were not gifts. As it stands right now, Fani has no way of proving that she repaid Wade for her share. In other words, there's no evidence (or paper trail) to show that all those many vacations were not gifts. Fani expects us to take her and Wade's word for it.
Regarding the start of the affair before Wade was hired, Merchant and the defense team already have sworn testimony of a close personal friend of Fani's (who was a former employee of the DA's office).
