Jill Biden announces more key staff for East Wing

Incoming first lady Jill Biden continues to round out her East Wing staff, announcing Thursday key hires in both her press office as well as a new executive director of her Joining Forces initiative.

Biden has tapped Rory Brosius to lead the re-launch of Joining Forces, which provides assistance to service members and their families and veterans. The announcement signals the return of the military support platform Biden co-founded as second lady with Michelle Obama, and indicates Biden intends to put focus on the military and military families. Brosius currently serves as the military families lead on the Biden-Harris Transition Team, and she was deputy director of Joining Forces under Obama.

Biden also named Michael La Rosa as her press secretary, who most recently served as her press secretary on the campaign and transition, acting as chief spokesperson for Biden. La Rosa previously was communications director for the House Democratic Policy Communications Committee.

In a statement, Biden noted the "varied and diverse backgrounds" of the incoming staff, saying, "These dedicated and accomplished public servants bring a shared commitment to building an administration that lifts up all Americans."

Biden also adds to the White House social office, bringing on Liz Hart, who will serve as deputy White House social secretary. Hart will work under incoming social secretary Carlos Elizondo, whose role was announced by the Biden team in November. 

Biden touted her desire to expand the scope of the first lady's initiatives.

"We will work to open the White House in new, inclusive and innovative ways, reflecting more fully the distinct beauty of all our communities, cultures and traditions," Biden said.
