On November 27, 1963, the new president delivered his Let Us Continue speech to a joint session of Congress, saying that "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."[108] The wave of national grief following the assassination gave enormous momentum to Johnson's promise to carry out Kennedy's plans and his policy of seizing Kennedy's legacy to give momentum to his legislative agenda.[109]
On November 29, 1963, just one week after Kennedy's assassination, Johnson issued an executive order to rename NASA's Apollo Launch Operations Center and the NASA/Air Force Cape Canaveral launch facilities as the John F. Kennedy Space Center.[110] Cape Canaveral was officially known as Cape Kennedy from 1963 until 1973.[111][112]
Also on November 29, Johnson established a panel headed by Chief Justice Earl Warren, known as the Warren Commission, through executive order to investigate Kennedy's assassination and surrounding conspiracies.[113] The commission conducted extensive research and hearings and unanimously concluded that Lee Harvey Oswald acted alone in the assassination. However, the report remains controversial among some conspiracy theorists.
