** FILE ** Then-FBI Director J. Edgar Hoover is seen in this 1972 black-and-white file photo. When Eugene McCarthy ran for president in 1968, he promised to fire Hoover, who had outlasted presidents from Calvin Coolidge to John F. Kennedy. Before long, McCarthy was denigrated in a fat FBI file as too "misguided" and "irresponsible" to serve in the White House. (AP Photo, File)
