Sigal Mandelker Departure (2019)
June 2017 - October 2019What Happened
Sigal Mandelker served as Under Secretary for Terrorism and Financial Intelligence during Trump's first term, overseeing the reimposition of Iran sanctions after the U.S. withdrew from the nuclear deal. She departed in October 2019 for the private sector, leaving the position vacant for over two years.
Outcome
Justin Muzinich served as acting Under Secretary while the administration struggled to find a permanent replacement.
The extended vacancy demonstrated how TFI leadership gaps can persist without disrupting day-to-day sanctions enforcement, though strategic direction suffers.
Why It's Relevant Today
Hurley's departure after just seven months contrasts sharply with Mandelker's 28-month tenure, suggesting deeper policy disagreements rather than routine private-sector departure.
