Spencer is the latest U.S. citizen to be cleared after contracting Ebola.
Dallas nurses Amber Vinson and Nina Pham also have been released from the hospital along with a missionary and three medical professionals who contracted the disease in Africa. Ashoka Mukpo, a freelance cameraman for NBC, also has been cleared of Ebola.
