Pretending the actual Pompeo subpoena document doesn't exist is a pretty stupid road to go down. Besides, who cares if we show it to you? You'll just weasel around having to admit you were wrong by declaring it to be bullying of Republicans and illegal, a witch hunt, circle jerk, whatever the nom du jour you have for something you don't like is when it happens.
If you read
Schiff's letter, he doesn't even mention the documents being subpoenaed!
... we are hereby transmitting a subpoena that compels you to set for the documents in the accompanying schedule by October 4th...
The subpoena document itself is a technicality. Just because it hasn't been published doesn't mean it doesn't actually exist. Let me guess, the House of Representatives are lying, and the entire media (all of it) is lying, but somehow you are right because you know better.
