President Javier Milei appoints Diego Santilli as his new Cabinet chief (chief of staff) following the resignation of Manuel Adorni. Multiple outlets report that Milei announces the change on Sunday, June 28, with Santilli’s formal swearing-in scheduled for Tuesday, completing a transition set in motion by Adorni’s departure. Adorni resigns amid a corruption investigation and, according to one report, he also blames the media. Santilli, a former interior minister and former PRO (center-right) figure, takes over as the fourth person to hold the post under Milei, reflecting frequent turnover in the role. One account notes the pace—four Cabinet chief changes in roughly 30 months—has drawn criticism and a university study links the turnover to weakening the importance of the position. Other coverage describes internal political coordination among several libertarian and opposition-aligned groups around the leadership transition. Santilli is expected to maintain involvement in government while stepping into the new role, with at least one outlet stating he continues as interior minister alongside the Cabinet chief appointment.
