From WashingtonPost.com:
Two campaign-finance watchdogs asked the Internal Revenue Service on Tuesday to investigate Crossroads GPS, the big-spending conservative group supported by Republican guru Karl Rove, for allegedly violating U.S. tax laws limiting the political activities of nonprofit groups.
In a complaint filed with the IRS, Democracy 21 and the Campaign Legal Center say the group - an arm of the American Crossroads political committee - is using its nonprofit status to shield the identities of its wealthy donors.
The complaint says "the group was organized to participate and intervene in the 2010 congressional races while providing donors to the organization with a safe haven for hiding their role."
Jonathan Collegio, spokesman for American Crossroads and Crossroads GPS, said the GPS group "carefully follows all laws" governing nonprofit organizations.
"This is a baseless complaint, filed by a partisan group that files baseless complaints for its living," Collegio said.
