From the article:
The nonprofit group pushing for disclosure, Citizens for Responsibility and Ethics in Washington, responded yesterday with a statement that the Justice Department has subpoenaed such officials without difficulty in the past. "It is astonishing that a top Department of Justice political appointee is suggesting other high-level appointees are unlikely to cooperate with legitimate law enforcement investigations. What is wrong with this picture?" said Melanie Sloan, head of the group."
A little searching reveals that Citizens for Responsibility and Ethics in Washington (CREW) provides legal counsel for the Wilsons, and its funding traces back to this group:
Democracy Alliance was founded by former Clinton Treasury official Rob Stein, Erica Payne and various donors in 2005. . ."At least 80 wealthy liberals have pledged to contribute $1 million or more apiece to fund a network of think tanks and advocacy groups to compete with the potent conservative infrastructure built up over the past three decades," The Washington Post reported in August, 2005.. .The Democracy Alliance tries to keep a low profile and its wealthy donors prefer anonymity. According to published reports, organizations funded by Democracy Alliance are asked not to reveal the funding. In 2006 a San Francisco, CA, office was established by the Democracy Alliance at the Presidio in the Tides Center, where Alliance member Drummond Pike has his offce. Rob McKay of the McKay Foundation and Anna Burger of SEIU are the elected chair and vice chair of the board of directors of the Democracy Alliance. [2] "Members of the Democracy Alliance include billionaires like George Soros and his son Jonathan Soros, former Rockefeller Family Fund president Anne Bartley, San Francisco Bay Area donors Susie Tompkins Buell and Mark Buell, Hollywood director Rob Reiner, Taco Bell heir Rob McKay ... as well as New York financiers like Steven Gluckstern."

Quite a "nonprofit" group.
