That one has focused on the IRS's "failure to enforce the law requiring that tax-exempt 501(c)4s be engaged exclusively in socialwelfareactivities, not partisan politics, " Levin said in a statement.
First, any effort to have the IRS police advocacy activities of social-welfare organizations is bound to be clumsy and prone to degenerate into either selective or broad witch hunts.
The IRS rules allow the tax-exempt entities to participate in those actions, as long as promoting socialwelfare remains the primary focus of the group's activities.
Unlike other charitable groups, these organizations are allowed to participate in political activities, but their primary activity must be socialwelfare.
