For Willis: under oath she claims the relationship started after she hired Wade. Other witnesses, say they started before. This timing is very relevant to the underlying issue. Lying to the court would certainly be illegal. I’m sure, if judge allowed for broader discovery, texts/emails would prove either way 100%.
For Wade: same thing as above. Additionally, he provided answers to the court in his divorce case that he now contradicts to this court. As example, he either did or did not entertain opposite sex up to the present. In divorce court he states no in this court he says yes.
If someone wants to dig deeper, there are probably other issues (not accounting for trips/cash payments on business account properly), campaign account claims (taking cash out), etc…
With stakes this high, someone is going to pull on all of these strings if they both stay on this case.
They are both really sloppy for this high profile of a case.
