My analysis of what Dershowitz said is not based on any "media" save that which broadcast the words directly from his mouth. He said that a president can take action in the "national interest" and his perception of "national interest" can include getting himself reelected. Seems to cover Nixon's perception of what he was doing. In fairness to Jackhammer, his remarks perhaps conveyed narrower immunity than did the more extensive remarks of the OJ dream steamer.
I meant mchammer. Damn autocorrect.
They had a direct quote from Trump too on Charlottesville. The narrative was fraudulent, because they ignored the context (including other words from Trump that were in direct conflict) in order to induce viewers and readers to believe something false and damaging. It's the kind of thing for which libel laws very clearly should be available but aren't.
This is Dershowitz's defense of what he said, for what it's worth. Link.
