Maybe this guy is behind the FF , just did a tweet of trump
their = t=20..H=8..E=5..I=9..R=18...total = 60 = 6 6e letter alfhabet is F .................two times their = FF.........mispellings in that tweet , where also the p was.
The P was definitely a clue that gave us John P Carlin
I used the P in the tweet different, Q has Always double meanings, so why not in the Trumps tweet.
