1) Anonymous column in NYT: 9/5/18
2) Haley GONE, poof, shocking the hell out of the entire political world, leaving with kissy-face Trump sitdown before the cameras: 10/9/18
3) From that moment forward, Trump has exhibited and exerted no - zip, zero, nada - further energy on the identity of Anonymous
There’s no proof Haley was Anonymous, and it’s really not worth further thought in any event, because after her departure the problem seems to be over if you measure by Trump’s behavior. Regardless, he is no longer concerned she might be any kind of electoral threat to him in 2020. Which she absolutely was.
