ABC to Interview George W. and Laura Bush in Africa

ABC News' Jonathan Karl talks to the former First Couple during their trip to Africa, which coincides with President Obama's trip to the region

ABC News Chief Correspondent Jonathan Karl will interview George W. and Laura Bush during their trip to Africa.

The Bushes are currently in Zambia to help renovate a clinic that will screen and treat cervical cancer as part of their work with the Bush Institute. On Tuesday, they'll join President Obama in Tanzania to lay a wreath at the site of the 1998 U.S. embassy bombings in Dar es Salaam, then host the Bush Institute's African First Ladies Summit.

Karl's interview will air on Tuesday during "World News With Diane Sawyer" and Wednesday during "Good Morning America." An extended version is set for Sunday, July 7, on "This Week With George Stephanopoulos," which Karl will anchor.
