My family often feels helpless in our search for our father, but we have never given up hope. One of the reasons we stay strong is because we have advocates like Sen. Bill Nelson. He regularly greets us when we travel to Washington to push Congress to act. He introduces us to other politicians and legislators in an effort to generate more commitment from his colleagues. He also willingly provides advice, context, and other guidance to help us strategize our next plan of action. It is precisely because of his time in Washington, with his deep knowledge of how to get things done and use the levers of power, that we cannot afford to lose him.
