MIAMI (AP) — The head of the Organization of American States is facing a call from the Biden administration for an external probe into possible misconduct tied to his intimate relationship with a subordinate. The Washington-based group’s own inspector general said this week it’s in the organization’s best interest to hire an outside firm to investigate allegations that Secretary General Luis Almagro may have violated the ethics code. That’s based on an Associated Press report that Almagro had a relationship with a staffer described online as his head adviser.
