At 4:11 a.m. EST Saturday, Lyndon Baines Johnson Jr. was sworn in as editor-in-chief of George magazine following the death of John F. Kennedy Jr. in a plane crash. 'At this tragic time in our magazine's history, let us look forward, remembering always the legacy of my predecessor,' said the 51-year-old Johnson, previously George's assistant editor, after being hastily sworn in by Chief Justice William Rehnquist on a New York-bound DC-10 jet. 'Let us now begin a process of healing, followed by a time of renewal at over 60 percent off the regular cover price.' The somber ceremony was witnessed by an estimated 15 George staffers and subscribers.
