In his retirement, Bush used the public spotlight to support various charities. Despite earlier political differences with Bill Clinton, the two former presidents eventually became friends. They appeared together in television ads, encouraging aid for victims of Hurricane Katrina and the 2004 Indian Ocean earthquake and tsunami. However, when interviewed by Jon Meacham, Bush criticized Donald Rumsfeld, Dick Cheney, and even his own son George W. Bush for their handling of foreign policy after the September 11 attacks.
