The fraud investigator who helped bring down former Trump aide Paul Manafort is back on the case — this time focusing on the ex-president himself. According to CNN, Morgan Magionos, a former FBI agent and member of Robert Mueller’s team, is working on Manhattan District Attorney Cyrus Vance’s sweeping probe into Donald Trump’s business interests. Vance reportedly brought Magionos on last year, as part of an accounting team from FTI Consulting. She spent nearly a decade working for the FBI as a member of its international corruption squad and is a certified fraud examiner and an accountant. Her investigation into Manafort led to multiple charges against the former Trump aide, including for bank and tax fraud, and she served as a “star witness” in his 2018 trial. Magionos is one of several recent high-profile additions to the Manhattan district attorney’s team, including the mob-busting prosecutor Mark Pomerantz, who’s noted for bringing down the head of the notorious Gambino crime family in the 1990s.
