George H.W Bush (“Timberwolf”)
The secret service is responsible for the safety of their charge until the completion of their term. As it turns out, it’s not uncommon for agents to continue to work with former presidents once they’ve left the White House. This is because of the close bond that is formed over the four years (which often turn into eight years, or two terms). George H.W Bush was called “Timberwolf” during his stint as president, and made such an impact on his detail that they tweeted about his kindness in recent years.
Barbara Bush (“Tranquility”)
As you can imagine, if the secret service is in a building protecting a president, they should always be incognito. When former first lady Barbara Bush passed away, one agent made their voice heard, talking about the fact that Mrs. Bush treated the detail as members of their own family. It’s no surprise that “Tranquility” was her nickname, especially as she appreciated when the detail was overly quiet, helping to maintain a peaceful environment each day.
