The bottom line is that, as Justice Department Inspector General Michael Horowitz concluded in his own 2019 probe—to Durham’s and Barr’s displeasure—the FBI investigation was amply justified. True, it ultimately found no evidence of acts that rose to the level of criminal conspiracy, and neither did the Mueller probe. But let’s not forget what did happen: Russian agents did conspire to influence the election, undermine Clinton and help Trump, and Trump as well as people close to him eagerly welcomed the help. (We didn’t need the FBI or Mueller to tell us that Trump was thrilled by the WikiLeaks disclosures of hacked documents from the DNC and the Clinton campaign: he said so openly and more than once.) What’s more, some people in the Trump campaign actively worked to take advantage of Russian meddling. Mueller’s indictment of Roger Stone states that after the first WikiLeaks dump, Stone and other “senior Trump campaign officials” made moves to find out what other compromising material WikiLeaks had. The charges against Stone, on which he was ultimately convicted, had to do with obstructing the investigation; but the only reason he couldn’t be charged with conspiracy for his attempts to establish contact with WikiLeaks is that WikiLeaks is not officially classified as a Russian asset.
