Not "national security" (which could be a domestic-only issue) but "foreign intelligence."
The crux of the issue is what justifies suspicion in the first place, that Trump's communications involve foreign intelligence?
Yes — what you said. :-)
“The crux of the issue is what justifies suspicion in the first place, that Trump’s communications involve foreign intelligence?”
Exactly. That’s what they’ve been pushing for months now, and like the predictable liars they are, they’re projecting. My biggest fear is that because Trump hasn’t been able to fully clean house yet and get his appointments through, there are still many Uniparty loyalists from the Obama and Clinton regimes in high enough positions to fabricate evidence against Trump. So many in our nation have been so dumbed down, and run on emotions, that with the help of the Ministry of Propaganda, they certainly could give it a good run, and probably will. If they do not succeed with this “silent coup”, there’s just too many of them looking at prison time for a multitude of issues, the very LEAST of which is Pedo/Pizzagate.
