Kamala Harris has sent another aide running for the hills. On Thursday, Sabrina Singh announced she accepted a new position with the Department of Defense.

The Daily Wire reports:

“We will miss her institutional knowledge, strategic counsel and rapid-fire email fingers,” Harris Communications Director Jamal Simmons wrote in a memo, which was obtained by CBS News.

Singh’s departure means just one of the four top communications positions in the veep’s office is left from the original staff on Inauguration Day.

The Post said she “is at least the ninth key official to depart the veep’s office since this past summer — joining director of digital strategies Rajun Kaur, director of advance Karly Satkowiak, deputy director of advance Gabrielle DeFranceschi, communications director Ashley Etienne, chief spokesperson Symone Sanders, director of press operations Peter Velz, deputy director of public engagement Vince Evans, and speechwriting director Kate Childs Graham.”

Singh’s resignation follows reports of “toxic” workplace behavior within the VP’s office.

Vincent Evans, deputy director of public engagement and intergovernmental affairs, in January quit to take on a new job on Capitol Hill, CNBC reported. He left to join the Congressional Black Caucus, which is headed by Rep. Joyce Beatty (D-OH), which certainly appeared to be less than a lateral move.

In December, Kamala’s top spokeswoman, Symone Sanders, and her Communications Director Ashley Etienne left the office.
