Earlier this month, Stephen Colbert took it upon himself to sign President Bill Clinton up for a Twitter account under the handle @PrezBillyJeff. Clinton dictated his first tweet to Colbert who sent it while they were filming a live episode of The Colbert Report in conjunction with the Clinton Global Initiative University retreat weekend held in St. Louis.
Clinton has since changed it to @billclinton, gotten verified, and started tweeting on his own. The training wheels are off and he's already got more than 300,000 followers. There's definitely a DM joke in there somewhere.
