John Wilke (1954, White Plains, New York – May 1, 2009, Bethesda, Maryland) was an American investigative reporter and news editor in the Washington bureau of The Wall Street Journal for two decades, beginning in 1989 and lasting until his death in 2009.
In July 1989, Wilke joined the Wall Street Journal's Boston bureau, covering technology. He moved to the Washington bureau in May 1995, covering economics and the Federal Reserve Bank until December 1996, when he began covering government technology policy, the Federal Trade Commission and the United States Department of Justice.
In 2006, private fraud investigator Harry Markopolos gave extensive details about the Bernard Madoff Ponzi scheme to Wilke, who showed interest in the story. According to Markopolos, Wilke's editors did not allow him to pursue the story.
From his obituary in the Journal: "In recent years, [Wilke] specialized in articles about deals cut by members of Congress to win special appropriations, known as earmarks, for friends, supporters and business associates back home. One of his investigations helped lead to last year's indictment of then-Rep. Rick Renzi (R., Ariz.), who is accused of receiving favors from developers and copper-mining executives in return for congressional help. Another revealed the broad range of earmarks a powerful Democrat, Rep. John Murtha, used to bring federal contracts to his Pennsylvania district."
- He won a Computer Press Association award with David Bank for his coverage of Microsoft.
- He won the Everett McKinley Dirksen (2007) prize for "distinguished coverage of Congress" for his reporting on congressional earmarks.
