There's an acronym for "circumstantial proof." It's "BS." Anybody can agree to say anything... like the moon is made of green cheese. It's circumstantial proof.
Circumstantial evidence is often weighed equally as direct evidence. Judges often tell jurys this, otherwise nobody would ever be convicted.
The common example is "If you walk outside and there's snow everywhere, do you ask yourself 'hmmm, maybe it snowed, but I didn't actually see it snow, so I can't be sure, maybe a bunch of guys came and spread snow all over my yard while I was sleeping...'
It snowed. But you only have circumstantial proof of it.
Insisting on direct evidence to prove you wrong is that flat earthers do.

Get them on the stand, with a verified copy of the subpoena, and under oath or affirmation, that it was served. Include the a copy of the Service affidavit, with the affidavit-maker attesting to it "viva voce" on the stand.
All the BS that these subpoena people are doing is to get Trump or some of his people to be scared and cave in.

This would all be circumstantial evidence.
