re: Trump tries to block release of book by 'traitor' John Bolton

I believe he said that he wouldn't voluntarily appear in the House, that he required an actual subpoena (which never came back then either - inquiry timeframe), and at the same time indicated he wouldn't honor such a subpoena prior to Mcgahn's subpoena case to being ruled on one way or another. I'm not certain what stage Mcgahn's litigation is in. So in other words, if Mcgahn's judge issued a ruling compelling his appearance before the House, then Bolton would follow in kind.

But ultimately, the exact same litigation would have occurred in the Senate that would have (or will) take place in the House. Bolton could take the oath, sit down in the hotseat, and it would be only at that point that the actual executive privilege would be asserted by Trump. So that litigation will or would have to happen regardless which chamber the subpoena comes from.

ETA....And I appreciate the polite and "professional" tone of your post. Just felt the urge to point that out. Thank you.
