The transcripts show that in July 2010, Elizabeth Hofacre, an IRS official in Cincinnati who was coordinating “emerging issues” for the agency’s tax-exempt unit, was corresponding with Washington-based IRS tax attorney Carter Hull.

In April 2010 Hofacre had been put in charge of handling tax-exempt status applications from conservative groups by her Cincinnati supervisor.

She was asked to summarize her initial findings in a spreadsheet and notify a small group of colleagues, including some staff in the Washington tax-exempt unit. However, she sent her email to a larger number of people in Washington by accident.

“Everybody in DC got it by mistake,” Hofacre said in the transcripts. She later clarified that she did not mean all officials but those in the IRS Exempt Organizations Rulings and Agreements unit.
