President Trump nominated Jamieson Greer to serve as the U.S. Trade Representative (USTR). In the first Trump administration, as USTR Chief of Staff, Greer worked closely with then-USTR Ambassador Robert Lighthizer, particularly with respect to tariffs and trade relations with China, and has represented corporations as a trade lawyer in private practice. If confirmed as USTR, Greer would be the United States’ top trade ambassador responsible for representing the U.S. in trade negotiation, monitoring U.S. trade agreements, and coordinating trade policy across the federal government.
