U.S. Legislative process

On July 4, 2025, President Donald J. Trump signed into law H.R. 1, the “One Big Beautiful Bill Act,” enacted as Pub. L. No. 119–21, 139 Stat. ___ (2025). Passed through the budget reconciliation process under the Congressional Budget Act of 1974, this comprehensive legislation represents a central pillar of the Trump administration’s second-term domestic agenda. It enacts sweeping reforms to the federal tax code, restructures discretionary and entitlement spending. The One Big Beautiful Bill Act does not suspend the debt ceiling through FY 2027. Instead, it raises the debt limit by a specific $5 trillion—an amount projected to sustain federal borrowing for roughly one to two years [i.e., until 2026–27, depending on fiscal trends].

Legislative History and Process

H.R. 1 advanced through Congress under budget reconciliation procedures, thereby circumventing the Senate filibuster and requiring only a simple majority for passage. This expedited pathway allowed the bill’s tax and spending provisions to be consolidated into a single legislative package and enacted swiftly along party lines.

The legislative branch of the United States government (embodied in Congress, which consists of the House of Representatives and the Senate) is the cornerstone of the federal lawmaking process and a central pillar of the constitutional system of checks and balances. Through its exclusive powers to enact laws, oversee the executive branch, and shape national policy, Congress functions within a broader framework of shared authority known as the separation of powers.

In this posting, we explore key questions surrounding the legislative process, followed by overviews of congressional powers beyond lawmaking, the practical operation of separation of powers, and the exercise of war powers in a divided government. Our goal is to provide material that will be useful to law and legislative librarians, the legal profession at large, and anyone whose work or civic responsibilities require engagement with these fundamental issues.
