A U.S. Senate committee investigating organized crime’s reach into gambling spent barely a single day in Las Vegas in November 1950, and left having accomplished almost nothing it set out to do. Nevada did not wait for Washington to finish the job. Within five years, the state built its own licensing police force, and that same regulatory apparatus — not the federal government — now oversees a gambling industry that posted more than $4 billion in revenue in a single quarter at the end of 2025.

The U.S. Senate adopted Senate Resolution 202 on May 2, 1950, creating the Special Committee to Investigate Organized Crime in Interstate Commerce, chaired by Sen. Estes Kefauver, a Tennessee Democrat, according to the Senate’s own historical account of its investigations. The committee opened its inquiry in Miami on May 28, 1950, and went on to hold hearings in 14 major American cities over the following year, the Senate’s history states.

Las Vegas was the committee’s only stop in Nevada, and it came on Nov. 15, 1950, after five months of hearings elsewhere, according to David G. Schwartz, a gaming historian who formerly directed UNLV’s Center for Gaming Research. Several casino figures the committee had subpoenaed, including Moe Dalitz, left town before the hearing and never testified, Schwartz wrote in his own account of the visit.

The committee heard from only six witnesses in Las Vegas, and most of their answers were evasive or amounted to flat denials, Schwartz wrote. One witness, Last Frontier Hotel executive and Nevada Tax Commission member William J. Moore, described a dispute over the wire service that fed racetrack results to the valley’s sports books, telling the committee that a casino figure’s demand for a cut of that service’s profits was building toward serious conflict. A former associate of that same figure, Moe Sedway, was questioned about the same dispute, according to Schwartz’s account.

The Las Vegas hearing lasted about a day in total: roughly two hours of testimony, a side trip to Boulder Dam, a short resumed session and a closing press conference, Schwartz wrote. Of the committee’s final report, which ran more than 11,000 pages nationally, only four pages concerned Las Vegas specifically. Kefauver had pushed for a 10% federal tax on all gambling revenue, but Nevada Sen. Pat McCarran blocked the proposal, Schwartz’s account states.

Nevada had already begun tightening its own oversight before the committee arrived. In 1949, under Gov. Vail Pittman, the Legislature expanded the Nevada Tax Commission’s authority over Las Vegas casinos and required every licensed casino to have access to the racetrack wire service for a fee, ending organized-crime figures’ control over who received it. In 1955, the Legislature went further, creating the State Gaming Control Board within the Tax Commission as its enforcement and investigative arm, according to the Nevada State Archives. At Gov. Grant Sawyer’s request, the Legislature passed the Nevada Gaming Control Act on March 30, 1959, removing the Tax Commission from gaming entirely and creating the Nevada Gaming Commission, with the Control Board serving as its audit and investigative arm, the Archives’ records state. The Board’s licensing-suitability regulations became the basis for Nevada’s List of Excluded Persons — the “Black Book” — issued March 29, 1960, naming 11 people barred from licensed gaming properties, according to the same state archive.

Seventy-six years after a Senate committee came and went from Las Vegas without landing a single meaningful blow against the city’s casino operators, the licensing system Nevada built in response is still the one running the industry. The Nevada Gaming Control Board’s own most recent quarterly statistics report shows the state’s casinos posted more than $4.1 billion in total gaming win between October and December 2025 alone, generating nearly $300 million in gaming taxes and fees for the state in that quarter. Nevada got the message Kefauver’s committee never quite delivered itself, and it built the regulator to prove it.
