Which senators and representatives cosponsored the Birthright Citizenship Act (S.304/H.R.569) in 2025?
Executive summary
The Birthright Citizenship Act of 2025 was introduced in the Senate by Sen. Lindsey Graham (R–SC) as S.304 and in the House by Rep. Brian Babin (R–TX) as H.R.569; the official congressional pages list multiple cosponsors but do not publish the complete names in the provided snippets, and outside summaries report differing tallies of supporters (sponsors: Graham and Babin) [1] [2] [3]. Public tracking services and advocacy groups show varying counts—Congress.gov reports 7 Senate cosponsors and 71 House cosponsors as of its snapshot while some summaries and advocacy write-ups reported smaller numbers [1] [2] [3].
1. The sponsors: who filed the bills and where the records point
The Senate version of the Birthright Citizenship Act of 2025, S.304, is sponsored by Senator Lindsey Graham (R–South Carolina), according to the Senate bill entry on Congress.gov [1], while the House companion, H.R.569, lists Representative Brian Babin (R–Texas) as sponsor on the House bill page [2]; both government bill pages and secondary trackers (GovTrack) identify the same pair as primary authors [1] [2] [4].
2. How many cosponsors are reported — and why the numbers vary
Official Congress.gov snapshots linked in reporting show differing tallies: the House cosponsor page for H.R.569 displays a summary figure of 71 current cosponsors and notes 35 original cosponsors in its snippet [2], while the Senate S.304 page shows a cosponsor statistic of seven current cosponsors, including two original [1]. By contrast, policy summaries such as the National Immigration Forum’s bill brief reported earlier or alternative counts—stating “2 cosponsors in the Senate and 51 cosponsors in the House”—which illustrates either a timing difference in updates or divergent aggregation methods across sources [3].
3. Which individual cosponsors are named in accessible reporting
Public trackers and bill-aggregation sites name a handful of individual House cosponsors in their excerpts: for example, FastDemocracy’s bill tracking output cites Representatives Dan Crenshaw, Earl “Buddy” Carter, and Derrick Van Orden among cosponsors of H.R.569 [5]. Beyond those named in the provided snippets, the government pages (Congress.gov/GovInfo/GovTrack) hold the authoritative lists, but the snippets supplied here do not enumerate the full roster; therefore an itemized list of every senator and representative who cosponsored cannot be compiled from the provided reporting alone [2] [1] [5] [4].
4. Political context, advocacy reactions, and what the cosponsor lists imply
The bill has drawn public opposition from child- and family-focused advocacy groups; for example, First Focus Campaign for Children sent a letter opposing the legislation and addressed that letter to the bill’s authors, Sen. Graham and Rep. Babin, framing the Act as a radical rewrite of the Fourteenth Amendment’s citizenship clause [6] [7]. That organized opposition points to the political stakes behind the cosponsorship tallies: cosponsor counts are often used as shorthand for intra-party cohesion or the level of GOP appetite for a high-profile immigration proposal, and different outlets’ varying counts reflect either snapshots at different dates or different definitions of “cosponsor” (original vs. subsequent cosponsors) [2] [1] [3].
5. What can be verified now and what remains uncertain from the provided reporting
From the supplied sources it is certain that S.304 was sponsored by Lindsey Graham and H.R.569 by Brian Babin and that both government bill pages list multiple cosponsors with aggregate counts shown in their summaries [1] [2]; it is also verifiable that at least some named House Republicans — Dan Crenshaw, Earl “Buddy” Carter, and Derrick Van Orden — are listed as cosponsors in third‑party trackers [5]. What cannot be authoritatively listed here from the provided material is the full, roll‑call list of every senator and representative who cosponsored each bill at a given date—retrieving that complete roster requires consulting the Congress.gov cosponsor lists or GovTrack detail pages directly [2] [1] [4].
