Jamieson has experience developing international trade compliance programs and training client employees, as well as managing international trade aspects of mergers and acquisitions for various industry clients.

Prior to joining King & Spalding, Jamieson was the Chief of Staff to the U.S. Trade Representative (USTR), Ambassador Robert Lighthizer. He worked very closely with Ambassador Lighthizer and senior White House officials on developing and implementing trade policy and advised the USTR on all aspects of the agency’s mission. Jamieson was also deeply involved in the Administration’s negotiations on the Phase One trade deal with China and participated in numerous strategy sessions with Ambassador Lighthizer, the President and other cabinet members as part of that process. He was a critical part of USTR’s efforts to negotiate and obtain Congressional approval of the new United States-Mexico-Canada Agreement. Jamieson participated in every major Administration trade action initiated during his three years at USTR.

Before working at USTR, Jamieson spent several years in private practice focusing on trade-related matters, from compliance with U.S. export controls to transactions subject to CFIUS’s approval, trade remedies and antidumping laws.

Jamieson also served in the U.S. Air Force Judge Advocate General’s Corps, including a deployment to Iraq. He served as both prosecutor and defense counsel in criminal investigations and courts-martial involving U.S. airmen.
