An Internal Revenue Service employee caught up in the controversy over tax-exempt groups wants a federal judge to block a subpoena for her videotaped testimony. The official, Holly Paz, cites privacy and safety fears.

A group that applied for tax-exempt status in 2012, Citizen Awareness Project Inc., sued the agency in Colorado federal district court, claiming officials wrongfully released its application to the media. Federal officials admitted there was an “unauthorized disclosure,” but they disagreed it was willful or that the group was entitled to damages.
