The U.S. Department of Labor handed over $275,000 in taxpayer-funded grants in 2009 to an organization that claimed to be a charitable nonprofit with tax-exempt status from the Internal Revenue Service.

But that organization was not officially certified as a 501(c)3 charitable nonprofit until 2010, documents show.

The Restaurant Opportunity Center, or ROC-United, a national organization working to raise the minimum wage and improve working conditions for restaurant workers by combing the labor organizing muscle of powerful unions with Occupy Wall Street protest tactics, got the grant anyway.

The group is organizing several high profile events this week to highlight the $2.17 national minimum wage for tipped workers.
