There’s no “discerning clue” leading to Comey, either, not even texts.
This cam pic from UK is the only thing I’ve ever seen to suggest a relationship between LP & anybody - how closely she & whomever - Comey or Strzok alongside - are walking, possibly with the man’s arm on or near. It wouldn’t surprise me that the “personal” texts etc. between LP + PS would be removed + redacted; but there’s nothing in-between the lines or sentiments conveyed other than their hate for Trump and love of HRC. TBD ;)
