Malcolm Emmett Lafargue (November 4, 1908 – March 28, 1963) was a United States Attorney from Shreveport, Louisiana.
He was known for his prosecution in 1939 as an Assistant US Attorney of several figures in the corruption scandals known as the "Louisiana Hayride." He achieved several convictions, including of Governor Richard W.
Leche, and many of these officials were sentenced to prison.
This ushered in a period of political reform in the state.
(Leche and other major figures soon received parole and were later pardoned by President Harry Truman.)
In 1950 Lafargue ran unsuccessfully for the United States Senate in a heated campaign against his fellow Democrat, Russell B.
Long, of the powerful Long family.
The Democratic Party had the only competitive contest in what was essentially still a one-party state.
"I have been fighting the Longs for fourteen years.
This isn't something new", said Malcolm Lafargue in his announcement of candidacy for the U.S.
