The House Oversight and Government Reform Committee has sent a letter to Lois Lerner's deputy demanding she clarify four aspects of her previous testimony in the IRS scandal that have since been challenged by documents obtained in the committee investigation or testimony of other IRS officials.

Oversight committee chairman Darrell Issa (R-Calif.) and Rep. Jim Jordan (R-Ohio), chairman of the subcommittee on Economic Growth, Job Creation and Regulatory Affairs, sent a letter to Holly Paz, the director of the IRS rulings and agreements of the Exempt Organizations (EO) unit, where she worked under EO director Lerner, now on paid leave since the scandal broke in May.

"The inconsistencies and contradictions contained in your testimony are of great concern to the Committee," the letter says after detailing its issues. "Therefore, to assist the Committee in its ongoing investigation, we ask that you please provide an explanation or amend your testimony as requested and necessary by September 3, 2013."
