Earlier this month, Bill Clinton sort of joined Twitter when Stephen Colbert set up an account for him under the handle @PrezBillyJeff. But now the former president is doing it for real, under his own name (@billclinton), on a verified account. The first message went out on April 6, around the time he and Colbert launched @PrezBillyJeff. The next three messages from late Wednesday are all to Colbert, so you know, he’s keeping it familiar. Apparently Chelsea is going to give him lessons.
