President-elect Donald Trump has nominated Jamieson Greer, an attorney and protege of former USTR Robert Lighthizer, as the United States Trade Representative (USTR). This appointment comes at a time when Trump is expected to pursue an ambitious trade agenda, focusing on imposing tariffs to address the country's massive trade deficit. Greer is tasked with defending American manufacturing, agriculture, and services, as well as opening up export markets. Trade policy will be significantly influenced by the finance departments at Commerce and Treasury.
