The whole premise of the conflict to begin with was whether House issued subpoenas served to the executive branch were legitimate or not, but don't let that stop you from jerking each other off in public.
No, it absolutely wasn't. You upped the ante from not being able to produce the Pompeo or Giuliani subpoenas to any subpoena related to the impeachment. Now you are doing some backtracking and while admitting the subpoenas exist you are now claiming they are not legitimate. That's an entirely different issue, one which I'm sure you know better than the house committees that issued the subpoenas. Whether or not you feel they are "legitimate" is besides the point.
Of course you can't even produce a document even resembling a subpoena from The House regarding impeachment before October 31st 2019.
Feel free to worm around some more.
No it is exactly the same issue from the start. Whether they are legitimate or not depends explicitly upon who they are issued to as the executive and legislative branches are co-equal. You still haven't produced the subpoenas under dispute no matter how thirsty you are to craft this tertiary bullshit into a win.
