“Instead of the Trump subpoena coming in a month or so, expect it delivered to Trump the day he leaves for the NK meeting. (See if I’m wrong here.)”
I agree that the Deep State, as represented by Mueller, would do that...if they could. However, you CANNOT subpoena a sitting President. It is something that both the Nixon and Clinton Justice Departments had as policy, and it has never been changed. The ONLY way to deal with a President who might have broken the law in any significant way is to go through the Constitutionally-authorized process of Impeachment. Even Mueller wouldn’t dare - this is a bluff, and intended to whip up a storm of controversy.
Instead of the Trump subpoena coming in a month or so, expect it delivered to Trump the day he leaves for the NK meeting. (See if I’m wrong here.) That is an interesting prediction. It implies that the entire effort is meant to sabotage his function as President.
I shall not be surprised if you turn out to be right.
