NEW: RFK Jr.'s running mate Nicole Shanahan releases powerful new ad telling RFK Jr. to "finish the job" his father and uncle started. Chills. "He felt in his heart cruelty and cowardice, the things that made him brave and kind," the ad read as JFK was assas*inated. "The Destiny of Man is to unite, not divide," the ad read as RFK was assas*inated. The ad ends with RFK Jr. endorsing Donald Trump and calling to Make America Healthy Again. "If you're going to do anything important with your life, there is going to be a hero's journey where you go through the valley of de*th, where you feel completely alone," RFK Jr. said. "The trick to life is to not have expectations but just to know what your duty is and just do it. You become relentless. Nobody can defeat you." Powerful. Video: @NicoleShanahan
