It's not called a subpoena. It's called a subpoena letter. The subpoena letter is in reference to the enclosed subpoena.
Then... PRODUCE THE SUBPOENA FROM BEFORE THE OFFICIAL VOTE
You claim it exists. Produce it.
Why? There wouldn't be anything in the actual subpoena that isn't in the subpoena letter, except maybe an address. FOIA requests take a couple months and cost like $50.
Subpoenas are published, public court documents. You don't need a FOIA request. Stop making excuses. It is a matter of public record. It never existed and you CAN'T PROVE it did. Just because some one wrote a note saying yeah we totally had that subpoena doesn't make it an actionable, filed, and processed court document.
