Academy Award®-winning actress Angelina Jolie took on the role of a lifetime when she became a Goodwill Ambassador for the United Nations High Commissioner for Refugees. As an ambassador, Angelina has made it her personal mission to raise awareness about the atrocities happening in the Sudan and around the world.

In April 2006, Angelina wrote a letter to USA Today and shared the "four facts Americans should know about Darfur."

In the letter, she writes: "I'm an actress and certainly no foreign-policy expert, but I've traveled to the region twice and believe that if Americans knew four simple facts that I've learned about Darfur, they would demand action from our government and would act themselves … We can stop this but only if government leaders make it a high priority."
