"Durbin Urges IRS to Investigate Spending by Crossroads GPS", Senator Richard Durbin press release, Oct 12 2010. Durbin wrote, "I write to urge the Internal Revenue Service to examine the purpose and primary activities of several 501 (c)(4) organizations that appear to be in violation of the law," wrote Durbin. "[Crossroads GPS] has spent nearly $20 million on television advertising specific to Senate campaigns this year. If this political activity is indeed the primary activity of the organization, it raises serious questions about the organization's compliance with the Internal Revenue Code.")
