I'm sure Pompeo, Giuliani and everyone else who has been served a subpoena over the Trump impeachment can prove their subpoenas exist. Why else would they bother going on public record to talk about them?
I am sure when a subpoena is created, by definition it is filed in a court of public record. Why would a public record not be available to the public? What prevents people from taking about it if it doesn't exist?
