DeMuth presided over the institute as a number of high-profile scholars joined AEI, including Charles Murray, Richard and Lynne Cheney, Michael Barone, James K. Glassman, Newt Gingrich, Karl Zinsmeister, and Ayaan Hirsi Ali. As many as twenty AEI scholars served in the George W. Bush administration. AEI scholars also influenced the administration. Announcing his departure from AEI in 2007, DeMuth noted that the Iraq surge strategy was devised at AEI. DeMuth oversaw the creation of an AEI magazine, the founding a joint center on regulation with the Brookings Institution (DeMuth was a fellow at the center), the expansion of AEI's publications, the founding of AEI's National Research Initiative to underwrite and promote research by university-based academics and independent scholars, a reorientation of AEI's foreign policy division to focus on the Middle East, and the merger of the National Legal Center for the Public Interest into AEI to form the AEI Legal Center for the Public Interest.
