In a major shakeup at the University of Southern California, which already is replacing its president, the school has announced that top legal officer Carol Mauch Amir and its academic provost are leaving on June 30.

The Tuesday announcement leaves three holes at the top of the school’s executive leadership team as it struggles to deal with two crises that carry major legal implications—the recent admissions cheating scandal and the allegations by some 600 students who say they were sexually abused by a former campus gynecologist. Both scandals remain under criminal investigation.
