Already on the look-out for a way to, in his own words, "become helpful", he had been made aware of this issue during a visit to Africa by Bono from the rock group U2.[200] The effort took place in partnership with the UN,[201] as well as MTV, which produced a documentary entitled Diary of Jay-Z: Water for Life, first airing in November 2006.[202] Along with Sean "Diddy" Combs, Jay-Z pledged $1 million to the American Red Cross's relief effort after Hurricane Katrina.[203] Jay-Z stated his support for Kanye West after the latter's outburst against President George W. Bush during a live Katrina charity telethon.[204] He also addressed the issue of the Katrina disaster, and the government's response, in his one verse song "Minority Report".[205]
