From time to time the discussion turned to the absence of a legal "predicate" to investigate President Donald Trump for colluding with Russia. That is, of course, important; and we can expect to hear a lot more about that in coming months.
More important: what remains unacknowledged is the absence of an evidence-based major premise that should have been in place to anchor the rhetoric and accusations about Russia-gate over the past three years. With a lack of evidence sufficient to support a major premise, any syllogism falls of its own weight.
The major premise that Russia hacked into the Democratic National Committee and gave WikiLeaks highly embarrassing emails cannot bear close scrutiny. Yes, former CIA Director John Brennan has told Congress he does not "do evidence." In the same odd vein, Brennan's former FBI counterpart James Comey chose not to "do evidence" when he failed to seize and inspect the DNC computers that a contractor-of-ill-repute working for the DNC claimed were hacked by Russia.
