The IRS has been accused of misusing its audit powers in addition to singling out conservative groups seeking tax exempt status.

In a series of special reports, Breitbart News is detailing additional stories of what appears to be IRS abuse and potential involvement from other agencies and possible Senate Democratic involvement.

The tax agency twice audited Idaho-based businessman Frank VanderSloot–once for his personal finances and once for one of his businesses in 2012 after President Obama’s re-election campaign placed him on a list with seven other donors to Mitt Romney’s campaign–and the Department of Labor audited one of his businesses as well. In addition a Senate staffer appeared in his hometown shortly thereafter seeking legal records on VanderSloot.
