Since there's a scheduled NSC meeting at Mar a Lago today at 4:00, I'm thinking that some of these top folks arrived last night and have already had late night meetings with Trump, prompting his 3:30 AM tweets.
The next several days are going to be very interesting indeed.
I don’t believe Trump would say such a thing without proof. In my opinion, it’s his way of telling jugears to back off or the heat will start falling his way.
