I was referring to the text in the complaint: The complaint is written off the legal discovery process, presumably in the case of especially a tech company such as Google, the statement that these teams met and discussed this topic would presumably be found in the form of either a meeting invite or the notes from a meeting sent in an internal email.

I think within some margin of interpretation, it's reasonable to state that if the text in the complaint is as such, it's backed by one or more internal emails I personally don't have access to. As I think it's pretty implausible that the Texas AG invented a meeting between the ad team and the AMP team and a reason for it out of thin air.
