There's multiple voices in the drops. One of them is clearly President Trump of course (Q+) and I suspect that's who Q was referring to when they made that statement.

I doubt it's Clancy or JFK Jr., primarily due to them both being dead.

McAfee, even if he is alive (which I won't rule out), would make little sense. He's an anarchist and hedonist. All known data on the man points to him never wanting to be part of a military intelligence operation. He was a man who deeply valued individual liberty, but I never sensed he had any great love of country.
