Princeton University’s announcement that it has hired President Joe Biden’s senior Iran envoy Robert Malley is full of praise for Malley’s career experience, and it notes that Malley is spending time this fall at the school while he is “on leave” from the State Department. In what I’m sure is an innocent oversight, the press release neglects to explain why Malley is suddenly on leave and available to spend a semester or more at Princeton in the midst of the administration’s ongoing negotiations with Iran.
