“All meetings” of public bodies, including “deliberations and proceedings,” are subject to the OML. A.R.S. § 38-431.01(A). But “a communication with the media that may [subsequently] reach a quorum of the board’s members is not a ‘gathering’ of the public body, and, for that reason, it is not a meeting.” Ariz. Att’y Gen. Op. No. I07-013.
