Lyndon Johnson
Johnson continued the push for civil rights that had been started by President John F. Kennedy. After JFK's assassination, President Johnson said in an address to Congress: "No memorial oration or eulogy could more eloquently honor President Kennedy's memory than the earliest possible passage of the civil rights bill for which he fought so long." The Civil Rights Act of 1964 was passed within months after the Kennedy assassination.
