This week, Clay Jenkinson's conversation with guest host David Horton about three remarkable moments in American history between administrations. First, the tragedy of Meriwether Lewis, who got caught between the outgoing administration of his mentor Thomas Jefferson and the incoming administration of President James Madison, who was no admirer of Lewis. This gap contributed to the nervous collapse of Lewis and probably his suicide in 1809. Then the burden that fell on the shoulders of Vice President Harry S. Truman in April 1945 when FDR died at Warm Springs and Truman learned about the existence of the atomic bomb and the Manhattan Project for the first time that day. And finally, the assassination of John F. Kennedy on November 22, 1963, and Vice President Lyndon Johnson's attempts to fulfill JFK's agenda on Vietnam, civil rights, and the space program.
