Symone Sanders, Harris' chief spokesperson, to leave White House

Symone Sanders, Vice President Kamala Harris' chief spokesperson and senior adviser, is leaving the Biden administration at the end of the year, according to a source familiar with the decision.

"Symone has served honorably for three years," the source told CNN. "The President and vice president are grateful for Symone's service and advocacy for this White House. She is a valued member, a team player, and she will be missed. We are grateful to have her working through the end of the year."

Sanders acknowledged her exit in a Wednesday letter to her colleagues, shared with CNN, in which she thanked Harris chief of staff Tina Flournoy.

"I'm so grateful to the VP for her vote of confidence from the very beginning and the opportunity to see what can be unburdened by what has been," the letter stated. "I'm grateful for Tina and her leadership and her confidence as well. Every day, I arrived to the White House complex knowing our work made a tangible difference for Americans. I am immensely grateful and will miss working for her and with all of you."

Her expected exit marks the second departure among Harris' top communication staff in recent weeks. Last month, a White House official told CNN that the vice president's communications director, Ashley Etienne, was leaving to pursue "other opportunities."
