"Robert Mueller and Leakin' Lyin' James Comey are Best Friends, just one of many Mueller Conflicts of Interest. And bye[sic] the way, wasn't the woman in charge of prosecuting Jerome Corsi (who I do not know) in charge of 'legal' at the corrupt Clinton Foundation? A total Witch Hunt," he wrote.

The woman prosecuting Corsi that the president referenced is likely Jeannie Rhee, a member of Robert Mueller's team who also represented the Clinton Foundation in a 2015 lawsuit and Clinton herself in a lawsuit seeking access to her private email. Rhee also donated thousands of dollars to Clinton's political action committee in 2015 and 2016.

The president also excoriated Mueller's "pit bull" attorney Andrew Weissmann, saying he "wrongly destroyed peoples lives."

"Will Robert Mueller's big time conflicts of interest be listed at the top of his Republicans only Report. Will Andrew Weissman's [sic] horrible and vicious prosecutorial past be listed in the Report," he continued. "He wrongly destroyed people's lives, took down great companies, only to be overturned, 9-0, in the United States Supreme Court. Doing same thing to people now."

The president was referring to the case against Enron's accounting firm, Arthur Andersen, which Weissmann prosecuted.
