A July 10, 1975 memo from then White House Chief of Staff Donald Rumsfeld to President Gerald Ford listed McGee as one of many potential candidates to be Director of Central Intelligence. Rumsfeld listed "pros and cons" of each candidate (including George Bush, Lee Iacocca, and Byron White and others). The memo thought McGee was a strong defender of the intelligence community, respected within the foreign affairs community, and well-regarded for his independence. On November 4, 1975, William Colby was replaced as CIA Director by George Bush in a major shakeup of President Ford's administration termed the Halloween Massacre.
