What’s happening with STOP Act?
The STOP Act, known as S. 4426, was referred to the Senate Committee on Health, Education, Labor, and Pensions on April 28, 2026. The committee members must now decide whether to hold a vote on the bill, but most legislation fails because committees choose not to act. This bill follows a similar proposal from December 3, 2024, that did not move forward before the session ended.
