Thomas E. “Tom” Donilon (born May 14, 1955) is the National Security Advisor in the Obama Administration, and has had a career as a U.S. political advisor, government official and lawyer. Previously, he served together with diplomat Wendy Sherman as Agency Review Team Lead for the State Department in the Obama transition, and as Deputy to National Security Advisor James Jones early in the Obama administration. Donilon replaced Jones as National Security Advisor on October 8, 2010.
Born in Providence, Rhode Island, Donilon attended La Salle Academy, earned a B.A. at The Catholic University of America in 1977 and a J.D. at the University of Virginia in 1985. He served on the Editorial Board of the Virginia Law Review.
He worked as Executive Vice President for Law and Policy at Fannie Mae, the federally-chartered mortgage finance company, as a registered lobbyist from 1999 through 2005. This line on his resume raised eyebrows when his appointment to the Obama transition team was announced, given that the company had been seized by federal regulators.
