I don't know if Mueller is fair and impartial, but I do know that from the beginning, Trump and many of his supporters and associates have been doing their utmost to stonewall and sabotage this investigation, not to mention the numerous complaints, whines and general hysteria transmitted in news outlets and on social media. Even though I don't like Gowdy, I agree with him here. Let the man do his job. Sure, it's disagreeable, but the more Trump, et al whine, grouse, complain and attempt to stonewall, the more it looks like Trump and his associates have something to hide. We don't know whether the things Mueller is looking at are related to the scope of his investigation or not. They could well be, or they could lead to evidence, of guilt or innocence. Would whiners like another sloppy, corrupt Hillary investigation where the outcome appeared to be pre-determined in her favor? Funny how those who complained about the half-assed Hillary's investigation seem to want want a similar investigation for Trump.
