Im having a hard time following this too....why would Blumenthal be interviewed about the dossier?
and when in 2016?
He was intetviewed by Mueller.
Maybe Steele indicated to the FBI that Blumenthal was a source for some of the information contained in the dossier. Steele was well-known and respected by the FBI. Steele helped uncover the crimes committed by the heads of international soccer and provided that information to the FBI. As a member of MI-6, Steele had many contacts with the FBI.
