FILE - This April 6, 2013 file photo shows former President Bill Clinton, left, and Comedy Central's Stephen Colbert during the Clinton Global Initiative at Washington University in St. Louis. More than 1,000 students from 75 countries and all 50 states are gathered for a weekend of sessions seeking practical and innovative solutions to the world's problems. Colbert lured the former president to the social networking site on “The Colbert Report” on Monday, signing him up with the handle PrezBillyJeff. Clinton dictated his first message to Colbert, who typed: “Just spent an amazing time with Colbert! Is he sane? He is cool!” Whether Clinton would continue to use the account remained uncertain. Colbert's hand is clearly in the account's description, too. It reads: “Stephen Colbert is my BFF.” By Tuesday morning, the account had quickly amassed nearly 50,000 followers and was climbing fast.
