In the aftermath of the 2004 Asian tsunami, U.N. secretary-general Kofi Annan appointed Clinton to head a relief effort. After Hurricane Katrina, Clinton joined with fellow former president George H. W. Bush to establish the Bush-Clinton Tsunami Fund in January 2005, and the Bush-Clinton Katrina Fund in October of that year. As part of the tsunami effort, these two ex-presidents appeared in a Super Bowl XXXIX pre-game show, and traveled to the affected areas. They also spoke together at the funeral of Boris Yeltsin in April 2007.
