Stephen Colbert lures Bill Clinton onto Twitter with handle PrezBillyJeff Former US President Bill Clinton and comedian Stephen Colbert take questions from the audience during the Clinton Global Initiative University at Washington University in St Louis, Missouri. BILL Clinton is now on Twitter, albeit without a very presidential name. Stephen Colbert lured the former president to the social networking site on The Colbert Report on Monday, signing him up with the handle PrezBillyJeff. Mr Clinton dictated his first message to Colbert, who typed: "Just spent an amazing time with Colbert! Is he sane? He is cool! Whether Mr Clinton would continue to use the account remained uncertain. Colbert's hand is clearly in the account's bio, too. It reads: "Stephen Colbert is my BFF." By Tuesday morning, the account had amassed nearly 50,000 followers and was climbing fast. Colbert interviewed Mr Clinton not in his New York studio, but at the annual Clinton Global Initiative University gathering in St Louis. The interview had been taped Saturday.
