Trump publicly claimed Mueller had conflicts of interest and was turned down for FBI job. Trump aides told investigators none of that was true.
Trump tweeted on July 29, 2018: "Is Robert Mueller ever going to release his conflicts of interest with respect to President Trump, including the fact that we had a very nasty & contentious business relationship, I turned him down to head the FBI (one day before appointment as S.C.) & Comey is his close friend."
Mueller’s report (p. 80, Volume 2) makes clear that Trump’s close aides told Trump there were no true conflicts of interests. Steve Bannon told Trump that one of his conflict of interest arguments — that Mueller disputed membership fees at Trump’s Virginia golf course — was "ridiculous and petty." Also, Mueller never went to the White House looking for a job, and the Justice Department cleared Mueller of ethical concerns preventing him from the special counsel role.
