Angelina Jolie's brother James Haven is following in his campaigning sister's footsteps, by travelling to Washington D.C. to join the fight against AIDS and Malaria in Africa.

Haven will meet senators Dick Lugar and Barbara Boxer in the capital on Tuesday to discuss the U.S. Government's commitment to the developing world.

While his sibling is a headline-grabbing United Nations Goodwill Ambassador, Haven, 34, isn't a stranger to charity - he is on the advisory board for the organisation Global Action for Children, and is a youth pastor at an evangelical church in Southern California, reports the Washington Post.

Jolie, 32 is currently in the capital herself, attending events and meeting with government bodies to continue her own work in the developing world.
