Vice President Harris is set to lose one of her closest and longest-serving aides in August with the departure of domestic policy adviser Rohini Kosoglu, whose planned exit follows a major shake-up of the office late last year and into the spring.

Kosoglu, 38, previously served as chief of staff in Harris’s Senate office and on her unsuccessful presidential campaign. Her decision to leave comes amid concerns among some Democrats about high turnover on the vice president’s team and Harris’s political viability at a time when President Biden is saddled with low approval ratings…

Harris’s chief of staff, Tina Flournoy, deputy chief of staff Michael Fuchs and national security adviser Nancy McEldowney left in the spring. That followed the departure late last year of several top aides, including chief spokesperson Symone Sanders and communications chief Ashley Etienne. In all, at least 13 staffers have left Harris’s office since last summer.

Some former Harris staffers have said the vice president’s demanding style has contributed to burnout. Supporters countered that the nation’s first female, Black and Asian vice president was being held to a double standard.
