James Comey, former FBI Director: "There should be no fuzz on this whatsoever. The Russians interfered in our election during the 2016 cycle. They did it with purpose.

In computer security parlance, fuzzing is the art of automatic bug finding. This is done by providing an application with semi-valid input. The input should in most cases be good enough so applications will assume it's valid input, but at the same time be broken enough so that parsing done on this input will fail. Fuzzing is mostly used to uncover security bugs.
