From a White House press release:
President Trump’s National Security Advisor Michael T. Flynn today announced the following additions to the National Security Council senior staff.
...
Kenneth I. Juster will serve as Deputy Assistant to the President for International Economic Affairs. He will coordinate the Administration’s international economic policy and integrate it with national security and foreign policy. He will also be the President’s representative and lead U.S. negotiator (“Sherpa”) for the annual G-7, G-20, and APEC Summits. Juster has previously served in the U.S. Government as Under Secretary of Commerce (2001-2005), Counselor (Acting) of the Department of State (1992-1993), Deputy and Senior Advisor to Deputy Secretary of State Lawrence S. Eagleburger (1989-1992), and Law Clerk to Judge James L. Oakes of the U.S. Court of Appeals for the Second Circuit (1980-1981). In the private sector, Juster has been a Partner and Managing Director at the global investment firm Warburg Pincus (2010-2017), Executive Vice President of salesforce.com (2005-2010), and Senior Partner at the law firm Arnold & Porter (1981-1989, 1993-2001). Juster has also served as Chairman of the Advisory Committee of Harvard’s Weatherhead Center for International Affairs, Vice Chairman of the Board of the Asia Foundation, and a member of the Trilateral Commission, the Council on Foreign Relations, and the American Academy of Diplomacy. Among his honors, Juster is the recipient of the Secretary of Commerce’s William C. Redfield Award and the Secretary of State’s Distinguished Service Award. Juster holds an A.B. in Government from Harvard College, a Master’s Degree in Public Policy from Harvard’s Kennedy School, and a J.D. from the Harvard Law School.
On twitter, Luke Peterson pointed out that Juster has worked in the investment arbitration field (e.g., here). Does that tell us anything about what a Trump administration will think of ISDS? More generally, I still have very little idea how the battle between establishment and anti-establishment members of Trump's international economics team will play out.
