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?
Are you sure congressional subpoenas require courts and aren't issued under their own authority?
What is a Congressional Subpoena?
Congressional subpoena power is defined as: the authority granted to committees by the rules of their respective houses to issue legal orders requiring individuals to appear and testify, or to produce documents pertinent to the committees functions, or both. Provided in clause 2(m)(1) and (3) of House Rule XI, House committees and subcommittees specifically have the authority to subpoena documents, information, and in-person sworn testimony at public and closed-door hearings; however, the conditions under which committees issue subpoenas can vary. For example, committee chairs often have to consult or notify the committees ranking minority members when issuing a subpoena. In some committees, the subpoena may be served by any person designated by the chair. Additionally, the subcommittees of the Appropriations, Armed Services, House Administration, and Transportation and Infrastructure committees are granted subpoena authority.

Regardless, these aren't just "people" talking about it -- they are the people to whom the subpoenas were served, acknowledging they have received subpoenas that you for some reason claim doesn't exist.

Rudy Giuliani:

Are you still insisting that the subpoenas don't exist?
