Maurice M. Milligan

Maurice Morton Milligan (1884–1959) was the United States Attorney for the Western District of Missouri whose office dismantled the Pendergast political machine that ran Kansas City. After the 1936 election, Milligan prosecuted the mass vote-fraud cases that convicted hundreds of machine workers, and in 1939 he secured the federal income-tax-evasion conviction that sent boss Tom Pendergast to Leavenworth. He later ran unsuccessfully for the U.S. Senate seat held by Harry Truman and recounted the campaign against the machine in his 1948 memoir Missouri Waltz: The Inside Story of the Pendergast Machine by the Man Who Smashed It.

Biography

Early life + legal career

Maurice Morton Milligan was born November 23, 1884, in Richmond, Missouri, the seat of Ray County northeast of Kansas City.¹² He earned both his bachelor’s and law degrees from the University of Missouri.¹² Before entering federal service he practiced law in Richmond and held local office as Richmond city attorney and as probate judge for Ray County.¹²

U.S. Attorney appointment

Milligan was appointed United States Attorney for the Western District of Missouri in 1934 and served the district as a federal prosecutor through 1945 — a total of roughly eleven years.¹² His tenure coincided with the height of the Pendergast machine, when Kansas City was governed under the patronage system of Tom Pendergast and city manager Henry McElroy.

His reappointment became a national political fight. In 1938 Senator Harry S. Truman — who had risen to the Senate with Pendergast backing — opposed Milligan’s confirmation on the Senate floor, attacking the fairness of the vote-fraud jury process. President Franklin D. Roosevelt nonetheless insisted that Milligan be retained, and the Senate confirmed him.³

The 1936 vote-fraud prosecutions

Milligan launched his assault on the machine after the 1936 general election, in which the machine’s ballot-box manipulation in Kansas City had been especially flagrant.¹⁴ U.S. District Judge Albert L. Reeves empaneled a federal grand jury and charged it to “reach for all, even if you find them in high authority.”¹ Milligan and his staff then prosecuted the resulting cases, obtaining convictions against 259 of 278 defendants — machine precinct workers, election judges, and ballot handlers.¹⁴ The prosecutions broke the machine’s control of the local ballot and exposed the scale of organized fraud in Kansas City elections.

Bringing down Pendergast (1938-39)

With the election apparatus discredited, Milligan’s office pursued Pendergast himself on federal income-tax charges. The case centered on a roughly $750,000 payoff Pendergast had taken in connection with a settlement of disputed fire-insurance rates, income on which he had failed to pay federal taxes.⁴⁵ Pendergast pleaded guilty to income-tax evasion in 1939; Judge Merrill E. Otis sentenced him to a fifteen-month federal prison term and a $10,000 fine, and Pendergast entered the federal penitentiary at Leavenworth in May 1939.⁴⁵ The conviction ended Pendergast’s reign over Kansas City and Missouri politics.

Later life + “Missouri Waltz” memoir

In 1940 Milligan ran for the Democratic nomination to the U.S. Senate seat held by Truman. The anti-Pendergast vote split between Milligan and Governor Lloyd C. Stark, allowing Truman to win the primary and retain the seat.¹² Milligan left the U.S. Attorney’s office in 1945.¹ In 1948 he published Missouri Waltz: The Inside Story of the Pendergast Machine by the Man Who Smashed It (New York: Charles Scribner’s Sons), his account of the campaign against the machine.⁶⁷ Milligan died June 19, 1959, in Kansas City, Missouri, and was buried in Sunny Slope Cemetery in his native Richmond.¹

Significance to Kansas City

Maurice Milligan is the figure most directly credited with ending the Pendergast machine’s grip on Kansas City. His vote-fraud prosecutions exposed how thoroughly the machine had corrupted local elections, and his tax case removed the boss himself from power, closing the “open city” era of the 1920s and 1930s and opening the way to municipal reform. Because the machine had launched the career of Harry Truman, Milligan’s work also sits at a pivotal hinge of national political history — and his memoir’s title, Missouri Waltz, pointedly invoked the state song Truman later favored.³⁶
