Education and legal career

Greer studied international relations at Brigham Young University, earned a law degree from the University of Virginia and completed graduate law studies in Paris. He served as an Air Force JAG officer, including a deployment to Iraq, and practiced trade and national-security law in the private sector.

Work with Robert Lighthizer

Greer was chief of staff to U.S. Trade Representative Robert Lighthizer from 2017 to 2021, involved in the administration’s China-tariff negotiations, Phase One agreement and U.S.–Mexico–Canada Agreement process. That is a documented employer/superior relationship with Lighthizer, not a generic link to any person who favored tariffs.

USTR appointment and institutional connections

The Senate confirmed Greer as trade representative in February 2025. His office leads U.S. trade negotiations and operates in the Executive Office of the President. Executive Order 14213 specifically places the USTR on the National Energy Dominance Council, connecting the office’s authority to the Burgum/Wright interagency framework.
