I don't know that the Durham Report uncovered violations of criminal statutes, with enough evidence to convict an individual or individuals for them. That is what would be required for indictments. If large numbers of indictments are the standard of success, the Mueller Special Counsel Assignment, the OIG Review, and the Durham Report were failures.
In fact, we know that the Mueller Report only concluded in reference to Trump that what it "does not exonerate him." The same is true for every special counsel report, every grand jury, and every criminal trial verdict. No one is "exonerated," in our legal system, which is a good thing. We don't want a system in which the accused is required to present enough evidence to convince those prosecuting him to exonerate him instead.
What the Durham Report uncovered, and read it
here for yourself, is a pattern of collusion between the Hillary campaign, the Obama White House, including Obama personally, the DNC, and the DOJ/FBI to generate phony accusations of Trump-Russia collusion to interfere with the campaign. No one of those conspirators ever objected to any part of the plan.
Adam Schiff worked behind the scenes to pressure researchers at a public university to participate in the sham.
As a secret operation, Crossfire-Hurricane has been largely exposed. I'm tempted to say "completely exposed," but there is no way to know whether, and how much, any additional malfeasance remains hidden.
