Norman Yung Yuen Hsu (Chinese: 徐詠芫), born October 1951, is a convicted pyramid investment promoter who associated himself with the apparel industry. His business activities were intertwined with his role as a major fundraiser for the Democratic Party, and he gained notoriety after suspicious patterns of bundled campaign contributions were reported in 2007. Subsequently he was discovered to have been a long-time fugitive in connection with a 1992 fraud conviction. After turning himself in to California authorities in 2007 he fled the state again and was quickly recaptured.
The U.S. Justice Department investigated whether Hsu illegally reimbursed political donations by associates and formally charged him with fraud. On November 27, 2007, a federal grand jury indicted Hsu on charges of violating federal campaign finance laws and defrauding investors "out of at least $20 million."
Hsu was born and raised in Hong Kong; his ancestors are from Shanghai.
