A Trump-backed top federal prosecutor in Nevada has been disqualified from handling criminal cases after a federal judge ruled that she is “not validly serving as Acting U.S. Attorney.”U.S. District Court Judge David Campbell ruled that Sigal Chattah, the interim U.S. Attorney for the District of Nevada, should no longer oversee criminal cases. The ruling came about when four men in Nevada were indicted on felony offenses. The men moved to have their charges dismissed, arguing that Chattah was not “validly” serving in her position, and asked for her disqualification from prosecuting criminal cases in Nevada. Chattah is disqualified from supervising these cases or any attorneys in the handling of these cases,” Campbell wrote. In August, a judge in New Jersey found that Trump’s former personal attorney, Alina Habba, was “illegally” serving as U.S. Attorney for the District of New Jersey.
