You have completely missed the point.
Whether you personally, because of your position, are confident that this information was unclassified/declassified is irrelevant. The average person/voter does not have access to that information.
Therefore, one way to clear that up in the minds of the public is by asking about it directly, ina public press conference. That's what would erase this as an issue.
You reiterating your own personal understanding does not address that point.
