The Americans for Prosperity Foundation, a conservative nonprofit with links to billionaire industrialists Charles and David Koch, is suing California Attorney General Kamala Harris for seeking the names and addresses of its donors, reports the Los Angeles Times. The federal lawsuit filed this week in Los Angeles claims the demand violates the foundation's First Amendment rights and that disclosure could pose risks to contributors' safety and economic livelihood.
California law requires charitable groups to submit copies of their Form 990s to the state. Ms. Harris' office warned Americans for Prosperity that its 2011 and 2012 state registration was incomplete because its 990s did not include the Schedule B form listing donors who gave more than $5,000 during the tax year. The attorney general's office asserted that, like the Internal Revenue Service, it would keep the donor information confidential.
In its filing, Americans for Prosperity said it has been registered in California since 2001 and had never been asked for donor data. The group was founded in part by the Koch brothers, who finance a network of nonprofits backing conservative candidates and causes, and is chaired by David Koch.
