The Independent now says the person of interest is Kushner.
EDIT: New York Magazine also backs this up, says four sources confirm (I believe that’s considered “innuendo” by our previous Trump standards). The First Family has been touched. This may well stir up another blind vindictive panic adding to the obstruction tally. The White House is already looking at taking measures that would completely coincidentally shield Kushner (and Manafort) from the Special Counsel.
