I don't think Steven A. Engel would agree with you that Schiff was only sending subpoena letters and not including the actual subpoena document. You're quoting him saying the subpoenas aren't legitimate, not that they were never served. Use your brain. Even if the subpoena was on the internet it wouldn't disprove any argument that they weren't legitimate, other than your silly "they only sent a letter, not the actual subpoena" argument.
That is exactly what he is saying. In order for the subpoenas to have been legitimate, they would have had to be served, or in this case, also "ratified" as he describes it. Since they were not, the subpoenas legally NEVER EXISTED. I would LOVE for you to prove me wrong on this. I am closing my eyes and sticking out my chin giving you a free shot. Prove me wrong. Find the subpoena you swear exists up and down in spite of having zero evidence of it ever being written.
No, that's not what he's saying lol. He's saying they sent a subpoena that wasn't properly authorized. You're saying they didn't send a subpoena at all.
