Question Author
Did, or did not the report which bears his name determine that there was "coordination" between the Russian government and individuals associated with the Trump campaign?
I, too, have no idea what "purview" means, but note it's onne of Mueller's favourite words. Ususually qualified (in hi congressional testimony) by the qualification [i]"not in my"[i].
The most interesting example of the "not in my purview" being when he was asked if he knew who the authors of the Steele report which created the conspiracy theory were, and who had solicited and paid for it.
The reliability of the theory's source document and the independence of its publishers (although there might be the a slight smack of Russian collusion) were not only outside Mueller's "purview", but seemed matters of little importance to America's most famous jurist since Wendell Holmes.
