Sep, 1974:
"In the debate over President Ford's pardon of his predecessor, the question of Richard Nixon's health emerged last week as a tantalizing issue. What role Nixon's mental and physical condition played in Ford's decision, and indeed what that condition was, were topics of conflicting reports and endless speculation. At week's end one fact became known: in a new attack of thrombophlebitis, Nixon has another painful blood clot in his left leg."
Hopefully Libby won't need one.
