No, it's not that kind of code. Mostly a nickname more than anything else. It is mostly tradition to give a "codename" to the President, VP, and their families.
The actual travel details of Presidential travel is highly classified, and they won't transmit in the open those details.
JFK = Lancer (I bet that was a bit of a double entendre)
Carter = Deacon
Reagan = Rawhide
Nancy = Rainbow
GHWB = Timberwolf (huh?)
BJ Clinton = Eagle (why?)
Hillary = Evergreen (what?)
Barbara Bush = Snowflake
Barry Hussein = Renegade
Moochelle = Renaissance (oh sure! I bet they had a real nickname for that b_tch)
Trump = Mogul
Melania = Muse
Moochelle=bigfoot
Okay, thanks for that information. I learned something.
Gee, my list of nicknames for most of the characters on that list is quite different....
“Hillary = Evergreen (what?)”
My first response to that was I’m wondering if Hillary is a Streisand puke (”Evergreen” is one of BS’s hits.)
Alternatively, wondering about the vampirism treatments for remaining youthful....
I read on an article about skull and bones - GHWB secret name was magog. Seems apt if all that’s been uncovered is true.
