No, that's not reasonable given the fact that the people who received said subpoenas have acknowledged their existence. They aren't Democrats, they aren't liberal media, they aren't me or TwitchySeal. They are extremely loyal employees of the president.

He's not making half-assed arguments about "due process" or questioning the fact that the subpoena exists. And his word trumps yours on this issue every day of the week.
People make assumptions. People are mistaken. People lie. The fact that a small number, or a large number of people think or say something does not constitute evidence of anything other than thoughts and ideas. I am not fighting anything. I am calling out the fact that you have the burden of proof of proving these subpoenas even existed, and you can not meet this burden of proof. People talking and thinking things is not meeting your burden of proof.
