Ben Affleck testified on Capitol Hill about security in the Democratic Republic of the Congo on Wednesday.
The actor founded charity the Eastern Congo Initiative in 2010 and has visited the war torn region several times since.
Ben's non-profit organisation supports several Congolese charities that are committed to rebuilding the region destabilised by militant rebels.
The Los Angeles-based actor traveled to America's capital Washington, D.C. to discuss his concerns for the country with the US House Armed Services Committee on Wednesday.
Lawmakers are currently reviewing security in the DRC and how it might affect national security in the US, USA Today reports.
The Argo director tweeted about his intentions to shed light on the situation this week. "Headed to the Hill on behalf of @EastCongoNews to talk about the evolving #DRC security situation," he wrote.
According to the newspaper, Ben is also spearheading a fundraising effort for his Eastern Congo Initiative that includes selling chocolate bars available online and in Whole Foods grocery stores to raise money for the organisation.
