Executive Order 13788, signed on April 18, 2017, directed federal agencies to strengthen enforcement of domestic content and workforce requirements across federal contracting and procurement operations. The order specifically mandated that agencies review and modify their acquisition regulations to maximize purchases of American-made goods and services while implementing hiring preferences favoring U.S. citizens and lawful permanent residents for federal employment positions. The mechanism relied on executive authority over federal procurement policy and personnel management, directing agencies to tighten compliance rather than establish entirely new statutory requirements.

The order's effects rippled through specific constituencies. Federal contractors faced increased scrutiny regarding the foreign content in their bids, potentially affecting companies with international supply chains. Federal agencies themselves were tasked with modifying hiring practices, creating measurable shifts in recruitment patterns for government positions. Small American manufacturers and domestic suppliers gained theoretical advantages in competing for federal work, though implementation varied significantly across departments. Job applicants who were U.S. citizens or permanent residents gained preference in federal hiring, while others faced formal barriers to consideration.

This action represents the opening salvo in a prolonged campaign prioritizing American manufacturing and domestic employment that would persist and intensify over subsequent years. The underlying philosophy—strengthening domestic content requirements and citizenship-based hiring preferences—anchors related policies signed years later, including the 2026 executive orders on "Truthful Advertising of Made in America Products" and the ongoing "National Emergency on Trade Deficits" declaration. These actions collectively pursue similar objectives: reshaping procurement toward domestic sources and framing trade policy through a protectionist lens. The 2026 initiatives demonstrate how the 2017 foundation expanded into broader regulatory and enforcement mechanisms.

The order achieved partial implementation status, reflecting uneven execution across federal agencies and shifting regulatory interpretations. Some agencies embraced the directive more aggressively than others, while legal challenges and administrative complexity limited uniform application. Complete reversal would require either a subsequent executive order explicitly rescinding these procurement modifications or congressional action to restore prior contracting standards and employment practices.
