Appeal to Authority, not even an informed authority.
Here's the citation proving it because you cannot be bothered to provide your own evidence. https://www.yahoo.com/news/opinion-trump-claim-revoke-biden-133000647.html
Trump is saying that some else used the autopen to sign documents without Joe's knowledge. That means they would not be legally valid. Wehle strawmans by saying that the objection is that they where done by autopen.
Nope, Trump said it was an issue for the courts to decide. "Knows" is a high standard that requires positive knowledge, it's likely that Trump suspects at this point and thus needs follow-up, or what is called an investigation to see if evidence exists.
You skipped right over that part so you can change the subject and not deal with the issue by lying about what I said with "So..DJT knows...gotcha! Sure man." as if that is the only bases ignoring the whistleblower and keep digging your hole deeper by lying.
I didn't claim he knows, that is a lie your keep telling, so you don't have to deal with the issue. It's possible, whistleblowers have said the autopen was used without Joe's knowledge, and it is a matter for the courts to decide that require proof.
Good thing Biden's legal dead weight still carries, huh? Yeah, keep those bribes and corruption coming! Multi-millionaire government workers could suffer. And the judges on the dole, oh my, they'll have to sell their mansions in the Catskills.
