Mr. Affleck is headed back to Washington. 

The 41-year-old activist and actor will join other experts in appearing before the Senate Foreign Relations Committee next Wednesday to discuss the humanitarian crisis in the Democratic Republic of Congo. The African country of over 75 million people has been the scene recently of increase violence against civilians; with an estimated 40,000 displaced due to armed militias terrorizing villages

Affleck's visit marks the second time in less than two years that he's testified on Capitol Hill; with a December 2012 appearance before the House Armed Services Committee.

"They deserve better than this cycle of violence and upheaval," he explained to members of Congress. "Without persistent, high-level leadership by the United States, the key players will not come to the table and do their part." 

In 2009, Affleck launched the Eastern Congo Initiative to further support for action in the DR Congo  - and the local actions in Conoglese communities that can be implemented to create social change. 

"I felt like I wasn't doing enough to give back to the world," he says in a recent campaign video for the organization. "So I found one of the most damaged, suffering places in the world, where 1 in 5 children die before the age of 5. It's a place where a million people are displaced, regularly, inside the country. Where there's the worst gender-based violence in the world…There are a lot of things to lament, particularly in the last 15 years when 5.5 million people died from conflict-related violence.

"No question in my mind, that down the road, when I'm an old man and I look back on my life, this will be the thing I most respect," he adds.
