The former US President was signed up during an interview with comedian Stephen Colbert and so far has only sent one tweet:
Just spent amazing time with Colbert! Is he sane? He is cool! #cgiu
The bio on the account, which has already amassed over 56,000 followers, appears to have been heavily influenced by Colbert: "I am President William Jefferson Billy Jeff Rodham Clinton. Stephen Colbert is my BFF." [Best Friend Forever]
The interview filmed on Saturday in St Louis for at the annual Clinton Global Initiative University and has since been promoting Clinton's new Twitter account:
Don't forget to follow @prezbillyjeff. I believe that as ex-president, everything he tweets carries the weight of law.
