Why did Barack Hussein Obama send $50 million to the Democratic Republic of the Congo?

Now being rather new to the blogging world, people can check all the facts they want to confirm or deny what I am about to post. I did an quick biography look-up on both presidential candidates and found some rather interesting information on Mr. Obama. Of all the legistlation that he initiated and sponsored, only one became law. If I am incorrect, my appologies. This would have been S.2125(109th) Democratic Republic of the Congo, Relief, Security and Democracy Act of 2006. This bill became Public Law No: 109-456. In short it provides approximatley $50 million (or more) American Taxpayer dollars to an uncertain and unreliable government. With this in mind, does Mr. Obama really represent the AMERICAN TAXPAYER??
