"Rules" & "Public Health" are different committees that have a say over such proposals. Apparently the Public Health committee postponed anything to do with it(?) on 3/1; it was assigned to Rules committee 3/5, who assigned it back to Health 3/6(??).

The assignment of a legislative measure to a committee.
Rules committee
Federally the Rules Committee, rather than being responsible for a specific area of policy, as most other committees are, it is in charge of determining under what rule other bills will come to the floor -VERY important! A rule is a simple resolution of the {federal House of Representatives}, usually reported by the Committee on Rules, to permit the immediate consideration of a legislative measure, notwithstanding the usual order of business, and to prescribe conditions for its debate and amendment
