Welcome to DC’s tent city

As homelessness deepens across the country, tent cities are becoming a familiar sight in some major cities. In Washington, D.C., a tent city has popped up a stone's throw from the United States Congress and the White House, underneath a highway that carries some lawmakers home. As this community has grown, Arnold Harvey, a local sanitation worker, has taken up the call to offer a helping hand, providing tents and supplies. In this America Tonight excerpt, we follow Arnold as he makes his rounds and speaks to some of the people who call this new tent city home.
