Ask that the IRS investigate mega churches like Joel Olsteen, Joyce Meyers, Benny Hinn, TBN and others. These churches have been the center point of scandals over and over again with their prosperity teachings. If they aren't hiding anything then they should be able to fully comply and finally clear their name if there is no wrong doing.
These churches ask people for money for healing and prosperity while they drive around in their expensive cars and jets and live in their huge mansions all tax free. Also recently John Oliver did a piece on just how easy it is to get tax exempt status and these churches appear to be taking advantage.
