WASHINGTON — 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.
