John McCain was a mentor to Kelly Ayotte in the U.S. Senate, and Ayotte has been asked to read from the Biblical Book of Wisdom at McCain's funeral service at the National Cathedral.
McCain will be eulogized by two men who dashed the two-time New Hampshire presidential primary winner's hopes at reaching the White House, Presidents Barack Obama and George W. Bush.
South Carolina Sen. Lindsey Graham, former Secretary of State Henry Kissinger, and former Connecticut Sen. Joe Lieberman will also give readings, as will several McCain family members.
President Donald Trump will not attend the funeral, nor will McCain's 2008 running mate, former Alaska Governor Sarah Palin, who was reportedly not invited to any of McCain's services in Arizona or Washington.
