Huber is a dud.
From the Fox article Q just linked
Republicans are increasingly looking for answers from U.S. Attorney for Utah John Huber, who was appointed a year ago by former Attorney General Jeff Sessions to review not only surveillance abuses by the FBI and DOJ, but also authorities' handling of the probe into the Clinton Foundation.
Huber, Republicans have cautioned, has apparently made little progress, and spoken to few key witnesses and whistleblowers. But in January, then-Acting Attorney General Matthew Whitaker reportedly indicated at a private meeting that Huber's work was continuing apace.
