The phrase “Senate Environmental Justice Caucus” does not appear in widely recognized encyclopedic references or major academic publications as an established, formally recognized entity. While individual members of the United States Senate have expressed interest in environmental justice and may participate in informal groups or working teams addressing related issues, there is no documented, permanent caucus with this exact title that is broadly acknowledged in authoritative sources.
Possible usage of the term could refer to a loosely organized gathering of senators who collaborate on legislation and policy initiatives aimed at promoting environmental justice, or it could be a provisional name for a newly proposed caucus that has not yet been formally constituted or widely reported. Without verifiable references, further detailed description would be speculative.
