Prove something that doesn't exist, doesn't exist? Is that how you think logic works?
You keep saying that but in this case your argument is bullshit. You can certainly prove the subpoenas exists or doesn't by requesting them. If they don't exist, they'll tell you that.. So backup your baseless claim and do it. You made the original claim and you can prove it so stop trying to deflect to some false logic argument.
Where's your proof that Pompeo said bigfoot exists?
I made the original claim... that the subpoenas didn't exist before the claim was made... that they did exist? Is that what you are telling me?
