Evidence: Controversial through his political and peace activism , he moved to Manhattan in 1971 , where his criticism of the Vietnam War resulted in a lengthy attempt by Richard Nixon 's administration to deport him , while some of his songs were adopted as anthems by the anti-war movement and the larger counterculture.
