Tim Morrison (presidential advisor)

Timothy Aaron Morrison (born c. 1978) is an American Republican political adviser. He was briefly the top U.S. adviser to President Trump on Russia and Europe on the White House National Security Council, a position he took over from his predecessor Fiona Hill in August 2019, and from which he resigned on October 31, 2019.

Before that, he served as senior director for countering weapons of mass destruction -- "arms control and biodefense issues" -- on the US National Security Council, a position he assumed on July 9, 2018. For about a year he was also responsible for pandemic response planning with the former staffers of the Council Directorate for Global Health Security and Biodefense, but was elevated to deputy assistant to the president. Prior to his administration positions, he had been policy director for the Republican staff on the House defense panel. Morrison entered politics as a professional staff member to Rep. Mark Kennedy, from 2000 to 2007. One day before his scheduled testimony to the impeachment inquiry against Donald Trump on October 31, 2019, Morrison was reported to be leaving his post soon as the senior director for European and Russian affairs on the National Security Council. He was to be replaced by Andrew Peek, at the time Deputy Assistant Secretary of State for Iraq and Iran in the Bureau of Near Eastern Affairs.

Morrison holds a Juris Doctor from George Washington University and a BA in political science from the University of Minnesota.
