The chief witness in the investigation into former Rep. Randy “Duke” Cunningham may have spilled the goods on more lawmakers than the now imprisoned San Diego Republican. According to Seth Hettena, the author of a book about Cunningham’s crimes, Mitchell Wade’s sentencing memo contains new revelations about his cooperation with federal authorities:

A 42-page sentencing memo filed by Wade’s attorneys says he aided the government in its investigation “of at least five other members of Congress” who were under investigation for “corruption similar to that of Mr. Cunningham.” These no doubt include Virgil Goode and Katherine “Pink Sugar” Harris. Wade wanted to open facilities in their districts and made $78,000 in “straw” contributions  to grease the wheels. Neither Harris nor Goode has been charged with wrongdoing.

Prosecutors drop tantalizing hints about an even bigger, ongoing investigation. Wade was debriefed in 2006 and provided “moderately useful” background information in another “large and important corruption investigation” that also has not yet resulted in any charges.

Who are the other 3 members of Congress? And what is this “even bigger, ongoing investigation”? Ken Silverstein has some speculation on who the 3 unmentioned members of Congress are.

Of particular interest is the way in which Wade revealed the information to law enforcement: he released a searchable, electronic database of 150,000 documents.
