John Durham and Donald Trump.Associated Press; Getty Images John Durham used Russian intelligence claims to obtain a US citizen's emails, per The New York Times. Durham was appointed by former Attorney General Bill Barr to examine the origins of the Trump-Russia investigation. But Durham pursued a dubious claim from Russia involving Hillary Clinton and an aide to George Soros. John Durham, former US Attorney for the District of Connecticut, was supposed to be investigating the investigators, charged with looking into the origins of what former President Donald Trump often termed a "hoax": the FBI's examination of his campaign's dealings with the Russian government.In the course of his hunt for wrongdoing, culminating in two failed prosecutions, the veteran prosecutor relied on dubious claims from the Kremlin to pursue a conspiracy theory involving Hillary Clinton, Democratic donor and right-wing boogeyman George Soros, and the former head of the Democratic National Committee, according to an investigation by The New York Times published Thursday.Durham, appointed as US special counsel by former Attorney General Bill Barr, had been told by a federal judge that his evidence was shoddy.
