We are with President Bush in Accra, Ghana, now.

Here are some more details on what Bob Geldof said to reporters in Rwanda that I didn't have time to post before we left for afternoon activities in Kigali.

Mr. Geldof said that he and Bono, U2's lead singer, have "gotten a lot of flak" for saying that Mr. Bush has done more for Africa than any other U.S. president.

Mr. Geldof said that "the main thing now is asking the candidates, 'What are you going to do?'"

Mr. Bush, said Mr. Geldof, has "put in place a whole foundation" in the form of aid for disease prevention, government institution building with accountability measures, and investing capital in African countries to build up their economies.

"The next guy really must take it on," Mr. Geldof said, referring to the next president.

While on Air Force One, Mr. Geldof spent about an hour with Mr. Bush in an interview that he is using for a piece in Time magazine and some European outlets.

He told me afterward, on the tarmac here after we landed, that one of his goals as an advocate for Africa is to create so much media attention around the issue of African aid and development that the U.S. presidential candidates are forced to visit the continent.
