Bush, and George W.

Bush were all Skull and Bones members.

The society operates from a building on the Yale campus known as the Tomb — a windowless, vault-like stone structure that non-members are not permitted to enter.

The society maintains strict secrecy about its internal practices, and members traditionally decline to discuss what happens inside the Tomb.

Various investigations and reports over the years have described the society’s initiation rituals and internal practices in general terms, often drawing on accounts from former members or people who claimed to have observed or learned about the proceedings.

Among the most persistent elements of Skull and Bones lore is the collection of human skulls and bones said to be displayed within the Tomb.
