To constitute the majority party's membership on certain committees for the One Hundred Nineteenth Congress, or until their successors are chosen.

This measure sets which senators from the majority party will serve on several key Senate committees for this Congress, or until new members are chosen. It covers committees that handle the environment, health, education, labor, homeland security, government oversight, the courts, intelligence, aging, small business, and the economy. By deciding who sits on these panels, it shapes which ideas get hearings, how agencies are watched, and what bills move forward.

Key committees named include Environment and Public Works; Health, Education, Labor, and Pensions; Homeland Security and Governmental Affairs; Judiciary; Intelligence; Aging; Small Business and Entrepreneurship; and the Joint Economic Committee. These committees affect issues like clean air and water, school and workplace rules, border and cyber safety, court confirmations, senior services, support for small businesses, and jobs and growth.

• Who is affected: Majority-party senators (committee seats), and indirectly the public through the policies these committees handle.
• What changes: Assigns majority-party membership for the listed committees.
• When: For this Congress, or until successors are chosen.
