collusion allegations

Ever since Deputy Attorney General Rod Rostenstein appointed former FBI Director Robert Mueller Special Counsel to investigate the Russiagate collusion allegations, there has been a huge amount of speculation about what if any information Mueller may have which he has not publicly divulged.
Mueller has however succeeded in running an exceptionally tight ship, with no leaks from his investigation to speak of.

Hot on the heels of the publication of the GOP memorandum (discussed by me here) has come another potentially even more extraordinary development in the Russiagate scandal.
This is the publication of a massively redacted version of the referral sent by Senators Grassley and Lindsey Graham to Deputy Attorney General Rod Rosenstein requesting that the Justice Department consider whether a criminal prosecution of Christopher Steele, the compiler of the Trump Dossier, should be brought.
