An additional 28 people affiliated with the Trump campaign have also been interviewed by either the special counsel or congressional committees probing Russian election meddling, the document notes. It does not name the people nor provide a breakdown of how many were interviewed by Mueller’s team.

I might be wrong but Mueller and company would not be interviewing that many people if
nothing was there.

BTW Alan Alda can play Bob Mueller in the movie.
