U.S. Former President Bill Clinton and former Secretary of State Hillary Clinton were among the guests at the State Funeral Service for former U.S. President Jimmy Carter on Thursday. The event was held at the Washington National Cathedral in Washington, D.C.

As Jimmy Carter's funeral commences, former presidents and first ladies are spotted greeting each other prior to taking their seats, except for one pair.
