The official at the center of the Internal Revenue Service tea party scandal once dismissed complaints that labor unions were not reporting millions of dollars in political activities on their tax forms, according to an email obtained by The Daily Caller News Foundation.

In 2007, Lerner responded directly to a complaint that some major labor unions reported completely different amounts of political expenditures when filing with the IRS and the Department of Labor.

At the time of the email, Lerner was the Director of Exempt Organizations at the IRS.
