The main purpose of this legislation, known as the "Drain the Swamp Act of 2025," is to require all executive agencies of the U.S. government to move their headquarters out of the Washington, D.C. metropolitan area. The goal is to decentralize federal operations and potentially reduce the concentration of government in the nation's capital. Key provisions of the legislation include a mandate for each executive agency to create a relocation plan by September 30, 2026.
