S. 181 has not moved since its introduction on Jan 22, 2025, with cosponsors, all Republicans

This bill requires federal agencies to submit zero-based budgets to the Office of Management and Budget and the congressional budget committees . Under the bill, a zero-based budget is a systematic budget analysis in which managers (1) examine current objectives, operations, and costs; (2) consider alternative ways of carrying out programs or activities; and (3) rank different programs or activities by order of importance. The bill also requires federal agencies to submit recommendations to reduce spending by at least 2% from the previous year's levels. The Department of Defense and the National Nuclear Security Administration are exempt from this requirement.
