The Victor Riesel acid attack was an assault on a reporter whose campaign against criminal influence in organized labor had made him a prominent public critic. In May 1956, a man threw acid into Riesel’s face outside a Broadway restaurant. The attack blinded him, but his later appearances urging labor reform helped bring the issue before a national audience and contributed to televised Senate hearings on racketeering in the labor movement.

Background and Attack

Riesel was an investigative reporter for the New York Journal American and used his daily radio program to feature Teamsters opposed to James R. Hoffa. He had been crusading against criminal elements in labor unions. On the night of the broadcast in May 1956, he stepped out of Lindy’s restaurant on Broadway, near Times Square. A man approached him on the sidewalk and threw a cup of acid in his face. The acid blinded Riesel.

The attack was soon attributed to an order from labor racketeer John Dioguardi, also known as Johnny Dio, an ally of James R. Hoffa. Dioguardi was charged with ordering the assault. But the case did not reach a conclusive public reckoning: the man who threw the acid was found dead, and other witnesses, having received the message, refused to cooperate. The charges were dropped.

Public Aftermath

The attack’s consequences extended beyond Riesel’s injuries. Blind and wearing dark glasses, he appeared on television and continued to urge labor reform. The persistence of that public campaign made the assault visible as more than a private act of violence: it became an emblem of the risks facing those who challenged racketeering within unions.

The resulting public outrage prompted the United States Senate to conduct live televised hearings on racketeers’ influence over the labor movement. These became known as the McClellan Committee hearings, after the Arkansas senator John L. McClellan, who presided. The attack thus helped turn an ongoing dispute over union corruption into a nationally televised political investigation.

Political Consequences

The hearings brought James R. Hoffa and Johnny Dio into the same public frame as the violence directed at labor reformers. Johnny Dio invoked the Fifth Amendment in response to every question, including whether he had ever met Hoffa. Hoffa, unable to invoke the same protection without forfeiting his union position, answered questions with evasions and claims of failed memory. When confronted with recordings of conversations with Dio, he denied recalling requests for favors.

Bobby Kennedy served as the committee’s chief counsel and principal interrogator. His aggressive work there helped make him James R. Hoffa’s mortal enemy. The acid attack’s significance in the book therefore lies not only in the blinding of a reporter, but also in the chain from a silenced witness and abandoned prosecution to public hearings and a sharpened political confrontation over organized crime and union power.
