Former president George H.W. Bush has joined Twitter.

The 41st president, who is 89 years old, drafted his first tweet Tuesday afternoon, sending his regrets that he couldn't make it to Nelson Mandela's memorial service.


Bush's spokesman, Jim McGrath, confirmed the authenticity off the account.


Bush has been dealing with health problems in recent years but is still seen regularly -- including his colorful socks -- at important national events.
