Symone Sanders, a senior adviser and the chief spokesperson for Vice President Kamala Harris, is expected to leave her position at the end of the month, a White House official and four other sources familiar with the matter told NBC News.

Her departure would mark the second high-level exit from Harris’ office in recent weeks. Ashley Etienne, the vice president’s communications director, announced last month that she would leave in December.

A White House official said Wednesday that Sanders had “served honorably” for three years, first as a part of President Joe Biden’s 2020 campaign and then on the transition team before joining the vice president’s office.

The official said the president and vice president were “grateful” for Sanders’ work on behalf of the administration and called her a “team player” who will be missed.
