By Paula Reid, Hannah Rabinowitz, Evan Perez, Casey Gannon, CNN(CNN) — Attorney General Pam Bondi’s chief of staff, Chad Mizelle, is leaving the Justice Department, the attorney general and her deputy confirmed in statements provided to CNN on Tuesday. Multiple sources said Mizelle’s departure is not related to Epstein, but nine months is a comparatively short tenure for a chief of staff. He has also served as acting associate attorney general – the third-most-senior position at DOJ. In his capacity as acting associate attorney general, Mizelle signed onto court filings and argued on behalf of the administration, notably defending Trump’s executive orders targeting large law firms. We are grateful for his service, and he will be greatly missed,” Deputy Attorney General Todd Blanche said in a statement.
