Joe Biden: Celtic
With the exception of former presidents, former vice presidents of the United States do not gain secret service for the longest time possible. Right after a VP steps down, the advantage comes to an end. But the Secret Service detail, former Vice President Joe Biden, returned when he wished to run for the presidency in 2020. And as his specifics came back, so did his code name for the Secret Service. In 2020, CNN announced that Biden would choose the code name “Celtic,” the same name as the vice president for this presidential campaign. An obvious nod to his Irish-American roots is the name.

Dwight Eisenhower: Providence and Scorecard
They should consider themselves lucky and successful if they have a Secret Service code name. But during his lifetime, former President Dwight Eisenhower had two different monikers. When he held the country’s highest office, Eisenhower was called “Providence” Since he does not appear to be related to the city of Rhode Island, nobody is quite sure why. And neither was Eisenhower sure of the nickname, it seemed. He changed his official name to ‘Scorecard’ when he left office, apparently based on his genuine enthusiasm for golf throughout his retirement.
