The leaders of six conservative groups are scheduled to tell lawmakers today about their mistreatment at the hands of IRS agents. Several of the groups say their applications for tax-exempt status were delayed while agents asked intrusive questions that the IRS has since acknowledged were inappropriate.

A report by an IRS inspector general said agents singled out conservative groups for additional scrutiny when they applied for tax-exempt status during the 2010 and 2012 elections.

The inspector general is scheduled to release another report Tuesday that says the IRS spent $50 million on conferences for employees between 2010 and 2012.
