The Internal Revenue Service is apologizing for inappropriately flagging conservative political groups for additional reviews during the 2012 election to see if they were violating their tax-exempt status.
Lois Lerner, who heads the IRS unit that oversees tax-exempt groups, said organizations that included the words "tea party" or "patriot" in their applications for tax-exempt status were singled out for additional reviews.
Lerner said the practice, initiated by low-level workers in Cincinnati, was wrong and she apologized while speaking at a conference in Washington.
Many conservative groups complained during the election that they were being harassed by the IRS. They said the agency asked them an inordinate number of questions to justify their tax-exempt status.
Certain tax-exempt charitable groups can conduct political activities but it cannot be their primary activity.
