LBJ's mistress, Madeleine Duncan Brown, was the most important witness to the JFK assassination plot that took place in Dallas. In her testimony, she explains a meeting that took place November 21, 1963 at "Clint Murchison's" estate and describes who was there and what was the meeting about.
Her testimony is explosive and all verifiable. Unfortunately, the "Warren Commission" has, of course, ignored her, just like other key witnesses that had very important information to uncover the truth.
