This memo and cover letter was received by Rex Bradford in August of 2002, after multiple inquiries regarding the discovery that one of the released LBJ conversations had apparently been erased. The conversation in question took place between President Johnson and FBI Director J. Edgar Hoover on the morning of November 23, 1963, less than 24 hours after the murder of President Kennedy. A transcript which has survived the erasure contains the stunning revelation that Hoover and Johnson knew that Lee Oswald had been impersonated in Mexico City prior to the assassination. See The Fourteen Minute Gap on the History Matters website for more information, and look in the November 1963 phone calls section of the History Matters Archive to view the surviving transcript (LBJ-Hoover 11-23-63).
