(CNN) - Donald Rumsfeld may soon encounter the world of known tweets, known unknown tweets, and unknown unknown tweets.
The former Defense Secretary is the latest celebrity of sorts to join Twitter, three months ahead of the release of his memoir, "Known and Unknown."
The account – with the handle @rumsfeldoffice – has already amassed close to 200 followers. While it appears to be more of a public relations organ than a personal account of Rumsfeld's, a spokesman tells CNN the former Defense Secretary will tweet himself "from time to time."
"He's deeply engaged in all the possibilities of new media," said spokesman Keith Urbahn.
