Not that I don't believe your completely wrong take on suborning perjury, but I gotta side with the AG nominee William Barr about suborning perjury over your wildly wrong claims:
“Thus, for example, if a President knowingly destroys or alters evidence, suborns perjury, or induces a witness to change testimony, or commits any act deliberately impairing the integrity or availability of evidence, then he, like anyone else, commits the crime of obstruction.”
