"Rex Tillerson is out as secretary of state, the White House announced on March 13 as he came back to the U.S. from a trip to Africa. Tillerson will be replaced as the nation’s top diplomat by CIA Director Mike Pompeo."
"In leaving, Tillerson lamented that Washington, D.C., can be a "very mean-spirited town." He told the State Department employees that "personal integrity" is the "most valuable asset you posses.""
"Tillerson is also known for his involvement with the Boy Scouts of America. He served as the organization's national president from 2010 to 2012."
