Lois Gail Lerner is an American attorney and former United States federal civil service employee. Lerner became director of the Exempt Organizations Unit of the Internal Revenue Service (IRS) in 2005, and subsequently became the central figure in the 2013 IRS targeting controversy in the targeting of politically-aligned groups, either denying them tax-exempt status outright or delaying that status until they could no longer take effective part in the 2012 election. On May 10, 2013, in a conference call with reporters, Lerner apologized that Tea Party groups and other groups had been targeted for audits of their applications for tax-exemption.

An investigation by the U.S. Department of Justice and Federal Bureau of Investigation, completed in 2015, found "substantial evidence of mismanagement, poor judgment and institutional inertia" but "found no evidence that any IRS official acted based on political, discriminatory, corrupt, or other inappropriate motives that would support a criminal prosecution."

In 1949, Swanson applied to the LL.M. program at the University of Virginia School of Law to pursue graduate work. He had recently opened his own law firm in Martinsville, Virginia, and wrote to the UVA Law Committee on Admissions that his "primary reason" for applying to the law school's LL.M. program was his "desire to teach." On January 12, 1950, the UVA law faculty voted to admit Swanson to the law school, and they sent the matter to UVA President Colgate Darden for a final decision. The University's Board of Visitors rejected Swanson's application on July 14, 1950 with the claim that his admission would violate Virginia state laws and the state constitution.
