Kennedy and Eisenhower both members of a secret society based on freemasonary?

The Elks originally borrowed a number of rituals, traditions, and regalia from the Freemasons. However, by the first decade of the twentieth century, much of this had been abandoned as the Elks sought to establish their own identity. The original two degrees required for membership were consolidated into one degree in 1890, the apron was discontinued in 1895, the secret password was gone in 1899, and the badges and secret handshake were abandoned by 1904.[40]

Initiation and funeral rituals still exist, however. The initiation rite is not considered a secret. The initiation involves an altar, with a Bible upon it and chaplain leading the brethren in prayers and psalms. The candidate must accept a "solemn and binding obligation" to never "reveal any of the confidential matters of the Order". He further promises to uphold the Constitution of the United States, protect brother Elks and their families, only support worthy candidates for admission and never bring political or sectarian questions up into the Order. The funeral rite is called the "Lodge of Sorrow" and also involves prayers.[9]
