"With the April 18, 2017, issuance of President Trump's Executive Order [EO] on Buy American and Hire American, U.S. procurement obligations with 57 countries under the World Trade Organization (WTO) Government Procurement Agreement (GPA), the North American Free Trade Agreement (NAFTA), and other U.S. free trade agreements (FTAs) are coming under scrutiny. Some may question whether the order, when implemented, could conflict with current U.S. obligations under these agreements. More specifically, could the EO run counter to U.S. policy on government procurement, which generally seeks to balance support for U.S. industries with ensuring a competitive, cost-efficient process?"
