The string of staff members in Vice President Kamala Harris’ office grows longer, as deputy chief of staff Michael Fuchs is now leaving the Biden administration, Fox News has confirmed.

First reported by Reuters, Fuchs’ departure was announced in an internal memo on Monday.

“It’s been the honor of a lifetime to serve in this administration, working for the Vice President and President on behalf of the American people,” Fuchs wrote in an email to fellow staffers. “Fifteen months later, it’s almost difficult to recall the magnitude of the challenges we faced when we came in, from an unprecedented pandemic to historically difficult economic circumstances. And it is thanks to the work of this administration – and all of you – that our country has had such success in tackling these challenges and turning things around.”
