St. Elmo's Hall appears to be a branch of the British Pilgrims Society. This society is controlled by the British monarchy and part of a litany of secret societies including Skull and Bones.

More info can be found here, but here is a short summary of what the reader will find.

1. DeSantis graduated from Yale and Harvard Law school.
2. Like George H.W. Bush before him, DeSantis played baseball at Yale. He is also connected with Dubya as he owned the Texas Rangers.
3. Joined the US Navy which is linked to British Admiralty and Pedophile culture.
4. Worked as a US Attorney, mostly in criminal cases where the defendant is represented by a public defender.
5. Q said to "watch the wives." Casey DeSantis is no exception. Her work includes work at TEGNA headed by Gina Bianchini who is a co-founder of Ming Interactive with Marc Andressen who is linked to the Pilgrims Society.

Conclusion: much more research needs to be done on the British Pilgrims Society because they clearly run the United States.
