Lois Lerner battles public scrutiny amid central role in Koch Brothers IRS controversy

From Wikipedia:

Lois Gail Lerner (born October 12, 1950) is an American attorney and former career federal employee. Lerner became director of the Internal Revenue Service’s Exempt Organizations Unit in 2005, and subsequently became the central figure in the 2013 IRS targeting controversy. Lerner resigned over the controversy. An investigation by the U.S. Department of Justice and Federal Bureau of Investigation, completed in 2015, “found no evidence that any IRS official acted based on political, discriminatory, corrupt, or other inappropriate motives that would support a criminal prosecution.”[
