WASHINGTON (AP) — Jill Biden has taken a step toward fulfilling a promise to revive a support program for military families that she and former first lady Michelle Obama once led. The incoming first lady on Thursday named an executive director to lead that program, known as Joining Forces. Jill Biden announced the appointment during an online listening session with organizations that support military families. Mrs. Obama and Jill Biden, as the wife of then-Vice President Joe Biden, launched Joining Forces in 2011. Joe Biden is set to be sworn in as president on Jan. 20.
