It's 2 paragraphs... What's the substance of the allegation?

He doesn't have a leg to stand on and he knows it. Otherwise he would empanel a grand jury and wait for indictments. He is a partisan sadist and he loves to use the legal system to abuse people.

It’s a similar nonsense letter to the same ones he sent to several prominent medical journals. Speech chilling, 1st amendment violating unsubstantiated threats on DOJ letterhead. Of all the unfit people in this administration, he’s likely the most unfit. His entire career has been deeply unethical and partisan and often borderline illegal.

The allegation is the substance.
