To quote from PR Newswire:
Today, Malaria No More, a nonprofit organization determined to help end malaria deaths in Africa, will bring former American Idol finalists Jason Castro (Season 7, 4th place), Melinda Doolittle (Season 6, 3rd place) and Elliott Yamin (Season 5, 3rd place) to Washington, D.C. to meet with members of Congress to voice American support for the malaria fight and celebrate the contributions of the U.S. Government.
They will also be performing at a reception tonight.
And Malaria No More put up this video last week:
As Jason says in the video, malaria is a disease we have the power to eradicate.
