Vice President Kamala Harris is losing another top staffer, according to reports.

Josh Hsu, who is Harris’ top legal adviser, reportedly said he intends to leave by year’s end, according to Axios on Wednesday.

Hsu, a Democratic lawyer, has worked for Harris since she was a U.S. senator from California, the report noted. He plans to enter private practice, Axios said.

In a statement to the outlet, White House Chief of Staff Ron Klain praised Hsu’s work and contributions to the Biden administration.

“Josh is an incredible legal mind, and this entire White House has greatly benefited from his talent,” Klain said.
