After investigating the allegations for five months and interviewing 15 witnesses, investigators were unable to find clear evidence that James knowingly falsified records to obtain better loan terms, ABC News first reported earlier this week.

James has denied wrongdoing, and her lawyer, in a statement on Friday, called the reported firing of Siebert a “brazen attack on the rule of law.”

“Firing people until he finds someone who will bend the law to carry out his revenge has been the President’s pattern — and it’s illegal,” Abbe Lowell said Friday morning in a statement to ABC News. “Punishing this prosecutor, a Trump appointee, for doing his job sends a clear and chilling message that anyone who dares uphold the law over politics will face the same fate.”
