The newest voice on Twitter is a veteran statesman: former president George H.W. Bush.
For his first tweet, Bush praised Nelson Mandela: "Barbara and I wish we could have joined the U.S. delegation honoring President Mandela today. He, and his countrymen, are in our prayers."
Bush, 89, could not make the long plane ride to South Africa.
