Sure, but he spoke to the majority of his consulting work as not being restricted by the NDA. He volunteered the information that some was NDA restricted, and requested release to offer further transparency. That doesn’t sound like an intelligent move unless he’s certain it would help his case.
Regardless, he still has no authority over the case at hand. I fail to see the reason for calling him out other than you read that he worked there in the past. I’m all for reading more evidence, if you have any to provide.
