This is another Trump game ... sort of like tweeting "COFEFE".  He was playing with Comey so that Comey wasn't sure how far he could carry any lies.  Trump has probably been enjoying watching the liberal media twisting themselves in knots over yet another innocent comment (he never said any tapes were made, only that Comey better hope there weren't any)!!  Good on ya' Mr. President ... keep playing with these liberal media morons until the world finally sees the buffoons they are!!!
