H.R. 28 prohibits school athletic programs from allowing individuals whose biological sex at birth was male to participate in programs that are for women or girls, effectively blocking transgender girls from women's sports nationwide by weaponizing federal Title IX funding.
---
What It Does
The bill provides that it is a violation of Title IX of the Education Amendments of 1972 for federally funded education programs or activities to operate, sponsor, or facilitate athletic programs or activities that allow individuals of the male sex to participate in programs or activities that are designated for women or girls. It shall be a violation for a recipient of Federal financial assistance who operates, sponsors, or facilitates athletic programs or activities to permit a person whose sex is male to participate in an athletic program or activity that is designated for women or girls. Any school receiving any federal funds—which includes virtually every public school in America—would be in violation if they allow transgender girls to compete on school athletic teams designated for girls or women. The bill applies to elementary school through college and covers intramural, club, and varsity sports. The only exception is practice or training together if no female loses a roster spot, playing time, or scholarship. Sex is defined as "reproductive biology and genetics at birth," meaning birth certificate sex. Violating schools lose federal education funding under existing Title IX enforcement mechanisms, which OCR can issue a formal findings letter and refer the case to DOJ or begin administrative proceedings to revoke federal funds. The bill requires a GAO report on impacts but doesn't condition the ban on findings from that report.

The Real Story
The core conflict is whether Title IX's ban on sex discrimination should be interpreted to allow schools to accommodate transgender athletes' gender identity or whether it requires sex-segregated sports based on biological criteria. The legislation is a cornerstone of the GOP's education agenda and would deliver on a priority for the incoming Trump administration. Supporters argue the bill protects athletic opportunities and bodily privacy for cisgender girls. Critics argue it weaponizes a civil rights law to exclude a vulnerable population and creates dangerous precedent for body surveillance. According to a recent New York Times poll, 79% of Americans believe that biological males who identify as women should not be allowed to compete in women's sports—suggesting public backing, though that poll doesn't separate K-12 from elite athletics where the stakes differ dramatically.

Who Benefits
- Republican Leadership and Trump Administration: Reps. Greg Steube (R-Fla.) and Mary Miller (R-Ill.), and Riley Gaines, a former University of Kentucky swimmer and ambassador for the Independent Women's Forum celebrated passage. The bill delivers a major campaign promise to Trump's base.
- Riley Gaines and Athletes' Advocacy Groups: Riley Gaines and more than a dozen other female athletes filed a lawsuit against the NCAA alleging that allowing men to compete in women's competitions denies women protections promised under Title IX, claiming the NCAA violates federal civil rights law. The bill provides legislative backing for their litigation.
- Conservative Organizations: Concerned Women for America, Family Research Council, and similar groups have made this a policy priority and will claim legislative victory, boosting fundraising and political mobilization.
- States with Existing Bans: 27 of the 50 states have restrictions in place regarding transgender athlete participation in sports. Federal legislation eliminates variation, protecting states' investments in these policies from court challenge.
---
Who Gets Hurt
- Transgender Girls and Women in K-12 and College Sports: The bill creates an absolute ban. About three percent of high school students identify themselves as transgender. These students lose access to school-based athletics, team membership, scholarships, and community participation that Title IX expanded for all girls.
- Intersex Students: The bill subjects women and girls in educational athletics programs—including intersex women and girls—to intrusive inquiries, improper scrutiny, and discriminatory harassment about their "reproductive biology and genetics at birth".
- Cisgender Girls Suspected of Being Transgender: Once schools implement sex verification mechanisms, any girl perceived as "too athletic" or not feminine enough faces invasive questioning.
- Schools and Universities: The bill failed to advance in the Senate with a 51-45 vote, meaning Senate Democrats blocked it. But schools receiving federal funding face immediate pressure from the Trump executive order (which parallels the bill) to choose between complying with the order or losing education dollars—even before Congress acts.
- National Education Association (NEA) Members: NEA members oppose the bill because it would exclude transgender students from participating in activities and opportunities that should be available to all students. The NEA represents 3 million teachers and education professionals.

Red Flags
- Vague "Reproductive Biology and Genetics" Standard (Section 1(d)(2)): Sex is recognized based solely on a person's reproductive biology and genetics at birth, but the bill provides no enforcement mechanism for determining this—potentially opening schools to invasions of privacy. In 2020, Idaho Governor Brad Little signed into law HB 500, a sports ban that allowed anyone to question whether a student athlete is a woman or girl, forcing the student to have to "verify" her gender by undergoing a physical examination. Under this type of law, a 10-year-old girl who seems "too tall" or even just "too good" could be targeted by officials and forced to release medical information or have her private parts inspected.
- Intersex Girls Will Be Harmed: The bill will exclude transgender girls from playing on teams with other girls—and will also inevitably exclude at least some intersex girls, with "reproductive biology" and "genetics at birth" as determinants creating ambiguity for intersex students. No exceptions exist.
- No Distinction Between K-12 and Elite College Sports: The bill's definition of 'athletic programs and activities' includes all programs or activities that are provided conditional upon participation with any athletic team, meaning a 10-year-old in recreational soccer faces the same federal penalty structure as a Division I athlete.
- Enforcement Mechanism Is Funding Cutoff with No Appeal: The ultimate penalty for non-compliance with Title IX regulations is the withdrawal of federal funds. Schools get no specific timeline to come into compliance and no formal appeal process before the threat of losing all federal education dollars (including student loans).
- GAO Report Buried in the Bill: The Government Accountability Office must report on the benefits for women or girls in single-sex sports that would be lost as a result of male participation. This report is ordered but no timeline given and findings don't modify the bill's absolute ban—making it largely performative.
- Inconsistent with Practice Exception: The bill does not prohibit male individuals from training or practicing with programs or activities for women or girls as long as such training or practice does not deprive any female of corresponding opportunities or benefits. But "opportunities or benefits" is undefined, inviting litigation from schools and athletes disagreeing on what counts as deprivation.

Hidden Riders
None identified. The bill is narrowly constructed to accomplish a single goal: amend the Title IX definition of sex in athletics.

Current Status
The bill passed in the House on January 14, 2025, on a 218-206 vote, with two Democrats joining Republicans to pass the measure. The bill is engrossed as of January 15, 2025, at 50% progression. It was received in the Senate for consideration but has not been scheduled for a Senate floor vote. An identical Senate version, S.9, also exists. In early March 2025, the Senate voted 51-45 on a cloture motion to advance S.9, failing to reach the 60 votes required to overcome a Democratic filibuster. The bill remains alive in Senate leadership's hands but requires either Republican defections on the Democratic side or Democratic defections to advance. Trump's February 5, 2025, executive order creates parallel enforcement pressure, so the legislative route faces uncertain prospects despite Republican House control. The bill does not have a fixed timeline for future Senate action.

Why now
Controversy erupted when Lia Thomas, a transgender athlete, became the first transgender athlete to win a women's national championship. President-elect Donald Trump honed in on transgender rights and inclusion as a key campaign issue and used it to attack Democratic candidates in ads and speeches. Trump signed an executive order on February 5, 2025, titled "Keeping Men Out of Women's Sports," directing federal agencies to enforce Title IX based on biological sex. This bill codifies into permanent law what Trump is attempting through executive action, making it a congressional priority as Republicans gained unified control of government.

Precedent
During the 118th Congress, the House passed the Protection of Women and Girls in Sports Act with a final vote of 219-203, split along party lines—the bill was not taken up by the Democratic-controlled Senate. This is a reintroduction of that failed bill, now with a Republican Senate. A majority of states have enacted their own laws governing who can compete in women's and girls' sports, often under titles like "fairness in women's sports" acts. Idaho's HB 500 became the template, but the bill is being challenged in the U.S. Court of Appeals for the 9th Circuit as an Equal Protection Clause violation in the case Hecox v. Little, where the plaintiffs initially lost in the District Court of Idaho, but the 9th Circuit Court of Appeals has yet to deliver a ruling. The federal courts remain split on whether sex-segregated sports bans violate the 14th Amendment. This bill attempts to short-circuit that litigation by defining sex legislatively, but courts may still strike it down as unconstitutional gender discrimination.

What to watch
The Senate is the key battleground. Though the House-passed H.R. 28 failed to advance in the Senate with a 51-45 vote on a cloture motion, falling short of the 60 votes required to overcome a Democratic filibuster—indicating it needs bipartisan support to pass but has not achieved it. Senate Democrats have successfully blocked identical versions twice. Watch for: (1) Amendment attempts to carve out lower age categories (youth sports) or lower competitive levels (recreation vs. elite), which could potentially peel off moderate Democratic votes; (2) Court rulings in pending cases (Hecox v. Little in the 9th Circuit) that might change political calculus; (3) Whether Trump's executive order enforcement creates political pressure by punishing states with transgender-inclusive policies before Congress acts. Citizens can contact senators on this vote—Senate pressure will determine whether the bill eventually passes or remains stalled.
