Hayden committed himself to the effort. For three years in Newark, he worked with a community union to organize poor black residents to take on slumlords, city inspectors and others. He was there to witness the 1967 Newark Riots which, in "Rebellion in Newark" (1967), he tried to place in a larger social and economic context. His profile in Newark attracted the attention of the FBI. “In view of the fact that Hayden is an effective speaker who appeals to intellectual groups and has also worked with and supported the Negro people in their program in Newark," agents recommended that he "be placed on the Rabble Rouser Index.”
