Joe Biden (“Celtic”)
Did you know that former vice presidents don’t gain secret service details when they leave office? The only exception to this is when a vice president has served, or will serve as a president. This is the case with current president Joe Biden, who has always been referred to as “Celtic” by the detail surrounding him. He has the same team with him now that was a part of his vice presidency under Barack Obama, and the name comes from his Irish-American upbringing.
Dwight Eisenhower (“Providence” or “Scorecard”)
Anybody who has been lucky enough to be given a code name from the secret service must have had a fairly interesting life so far. When Dwight Eisenhower was president, he was double as lucky, as he got to go by two different monikers over the years. During his presidency, he was called “Providence”. The nickname had no personal affiliation to him. After his term came to an end, he changed it to “Scorecard”, in a nod to his passion for golfing in retirement.
