The launch of Earth Day in 1970 raised suspicions in Washington, D.C., according to former Representative Pete McCloskey, one of the organizers of the first Earth Day.

The annual event was launched as a national teach-in on April 22, 1970, by former Senator Gaylord Nelson, McCloskey and others. Earth Day galvanized a political movement that led to some of the country's most significant environmental legislation, including the Endangered Species Act and the Clean Water Act.
