Attached to Hoover's letter was a four-page memorandum, whose flavor may be appreciated from the following paragraph:
It seems that Dr. ----- is a Lieutenant in the Navy, assigned to the Bethesda Naval Medical Center and residing at -----. When interviewed on October 27 relative to any statement which had been made concerning the state of the President's health, Dr. ----- denied making any statements of this kind, but stated that the President's health had been the subject of a general discussion at a luncheon recently held at the Naval Hospital in Bethesda. When asked to name specifically the persons who had attended the luncheon, Dr. ----- declined to do so and stated that the reason the President's health had been discussed at the hospital was because members of the hospital staff recognized the picture of one of the Navy Hospital doctors, Dr. H. G. Bruenn on the President's train at the time he was making the acceptance speech. Dr. ----- stated that he had not discussed the subject of the President's health with Dr. Bruenn. Dr. ----- was obviously disturbed and uneasy during the interview.The memorandum also recounts that a leading specialist from the Mayo Clinic, who had recently returned to Minnesota from a temporary assignment to Bethesda Naval Hospital, was interviewed by the FBI simply because he had made the statement that "the President has a serious heart ailment" while at a luncheon in Washington.
Hoover's letter summarizes by saying that there was "a lot of loose conversation and talk, all predicted [predicated?] upon the supposition that the President was suffering from some heart ailment by reason of the fact that Bruenn's picture appeared in the group with the President." 1
