as a visiting professor at the School of Public Policy and Management and at the College of Education and Human Development, and as a visiting Fellow at the Center for Education Policy and Evaluation. Interim President of George Mason University In June 2019, George Mason University announced that Holton would serve as the interim President of George Mason University beginning August 1, 2019. She remained in that role until Gregory Washington took office on July 1, 2020. First Lady of Virginia Following Thomas Jefferson's daughter, Martha Jefferson Randolph, Holton was the second daughter of a Virginia Governor to become First Lady of Virginia. Holton was the only person to live in the Virginia Governor's Mansion as a child and as an adult. As First Lady, she launched the "For Keeps: Families for all Virginia Teens" initiative in January 2007. The initiative focused on finding stable families willing to take in Virginia children in foster care, especially older or difficult-to-place children. In doing so she said was motivated by an urge to fix some of the problems she had witnessed in the foster care system during her stint as a judge in the juvenile court. During the 2008 presidential election, her husband was an early endorser of Barack Obama and Holton headed the state's Women for Obama group. Role during the 2016 presidential campaign In 2016, Democratic Party presidential nominee Hillary Clinton selected Holton's husband Tim Kaine to serve as her running-mate. Following her husband's selection as Clinton's running mate, Holton began traveling the country campaigning for the 2016 Democratic ticket. Immediately after the 2016 Democratic National Convention, Holton joined Clinton and Kaine on a bus trip through Pennsylvania and Ohio. She continued campaigning, sometimes appearing with her husband and sometimes alone, in several states. Holton discussed policy surrounding childcare and initiatives for small businesses when campaigning. During the campaign, there was speculation that if her husband were to become vice-president, Holton might fill the vacancy that would be left in Kaine's senate seat. Holton denied having any interest in the position, saying, in reference to the Vice President's role as President of the Senate, "I will never let (my) husband be my boss". Civic involvements and personal life Holton sits on numerous boards, including Voices of Virginia's Children, the Richmond Public Schools Education Foundation, and the advisory board of Youth-Nex, the University of Virginia Center to Promote Effective Youth Development
