A White House official told CNN Thursday that Tina Flournoy, Vice President Kamala Harris’ chief of staff, will leave her position this spring.

Flornoy is set to replace Lauren Falls, a veteran Democratic communications analyst who joined Harris’s office as an advisor last summer. Voles will focus its efforts on “organizational development, strategic communications, and long-term planning,” an official told CNN at the time.

In an email to employees obtained by CNN, Flournoy said she was “eternally grateful to the vice president for giving me this wonderful opportunity” and thanked the staff.

“It was my intention to speak to all of you individually to let you know that I will soon be leaving the vice president’s office and my role as chief of staff,” she wrote, noting that news of her exit may break before she can. to do that.

“However, I will speak to you in the coming days. I will then say–in much more poetic language, no doubt–that it has been a great honor to work with the Vice President and it has been a pleasure getting to know Kamala Harris and seeing for herself the great passion she brings to her job.”

Washington Post The news of Flornoy’s exit was first reported.

Flournoy is the latest in a Long series of departing journeys From the vice president’s office, that shook several times In recent months. Flornoy’s deputy Michael Fox announced earlier this month that he was leaving the administration. The White House recently confirmed that National Security Adviser Nancy McKildowne will be stepping down, to be replaced by her deputy, Phil Gordon. And Harris’ communications team got an almost complete makeover in recent months, after her communications guide Ashley Etienne, chief spokesman and senior advisor to Simon Sanders and deputy press secretary Sabrina Singh left the office within months of each other.

Flournoy, who joined the team at the start of the operation, led the office during a rocky vice president summer, during which Harish was criticized after several messaging errors and staffing issues. Republicans have seized on any obvious gaffes, relentlessly targeting the vice president.

One of Flournoy’s toughest moments came after countless reports of dysfunction overtook the office’s message, many of them centered around the chief of staff’s leadership — and thus Harris’s. Voles is set in the middle of those summer reports.

Harris, in a statement Thursday, paid tribute to her departing employee.

“Since day one, she has led our team through a historic first year as we made progress in rebuilding our economy here at home and our alliances around the world,” wrote Harris. “Tina is an accomplished public servant and I will continue to rely on her advice, counsel, and friendship.”

White House Chief of Staff Ron Klein, whom Flornoy knew before she joined the White House, praised her as “an important member of the White House team from day one, working with the president and vice president to make their partnership effective and help the administration deliver critical priorities.”

“Her experience, wisdom, and hard work have been instrumental in our success on many issues,” Klein said.

This year, aides saw the first few months of Harris’ second year as particularly successful for the vice president – she recently managed to navigate key foreign policy moments to avoid discord, including high-profile trips to Germany and Poland amid the Russian invasion of Ukraine, which It helped cement her place among President Joe Biden’s top envoys to a continent embroiled in conflict.
