Sen. Markwayne Mullin (OK): what he’s backed — and who it harms
1) Most consequential anti-LGBTQ / transphobic actions
- Led a Senate push to block trans inclusion under Title IX.
Mullin co-led a GOP letter “rebuking” the Education Department’s Title IX rule for “allowing biological males in women’s sports,” urging schools not to recognize transgender girls’ participation. Markwayne Mullin - Federal sports bans targeting trans girls/women.
He has repeatedly backed the “Protection of Women and Girls in Sports Act” — including the 118th-Congress bill (S.613) and the 119th-Congress bill (S.9) — which would bar trans girls/women from girls’/women’s school sports nationwide. Congress.gov+1 - Earlier House effort against trans student athletes (with Tulsi Gabbard).
As a House member, Mullin co-introduced an end-of-2020 bill attacking trans students’ participation in sports; the National Center for Transgender Equality condemned it as a “transphobic ploy.” A4TE - Rhetoric/amplification.
He has promoted the federal sports ban on social platforms and in press. X (formerly Twitter)
2) Most consequential anti-immigrant actions & statements
- Laken Riley Act (S.5, 2025): co-sponsor and vote to pass.
Requires DHS to detain undocumented people arrested (even before conviction) for theft/burglary and expands state power to sue the federal government; passed the Senate with Mullin’s support. Congress.gov+1 - Mass-deportation framing & family separation stance.
In a June 2025 interview, Mullin said U.S.-born children of deported parents should “go where their parents are,” effectively endorsing family removal and undermining birthright-citizen protections in practice. Reuters+2Newsweek+2 - Making border crackdowns “permanent.”
He has repeatedly touted “historic investments” for deportation operations and border infrastructure in the “One Big, Beautiful Bill.” Markwayne Mullin+1
3) Anti-diversity / anti-DEI signals
- Anti-DEI positioning around defense policy.
Mullin has publicly derided DEI in the military (e.g., “They didn’t sign up to be part of DEI… the ‘woke’ movement.”) and pushed NDAA provisions limiting pronoun use and DEI-style requirements in DOD communications. Newsmax+1
While the House has carried marquee “DEI-to-DIE” bills, Mullin’s public statements and NDAA rider support show a clear federal anti-DEI posture. Congress.gov
4) Oklahoma’s current policies — and how they harm Oklahomans
- Ban on gender-affirming care for minors (SB 613, 2023).
Oklahoma law criminalizes gender-affirming care for people under 18 (surgeries and hormone therapy/puberty blockers), worsening access and mental-health outcomes for trans youth. Welcome to Oklahoma’s Official Web Site+1 - Statewide trans bathroom restrictions in schools (SB 615, 2022).
Requires public-school bathrooms/locker rooms to be used only by sex on original birth certificates; litigation continues. Oklahoma Senate+1 - Birth-certificate restrictions (EO 2021 + SB 1100, 2022; ongoing litigation).
Oklahoma banned nonbinary markers and stopped corrections of gender markers on birth certificates; the 10th Circuit revived a challenge, and the state is seeking U.S. Supreme Court review. Reuters+1
How this damages residents:
Blocking medically recommended care and accurate documents increases suicidality and harassment risk among trans Oklahomans, while school bathroom bans intensify bullying and absenteeism. Immigration crackdowns and detention-on-arrest policies separate families and chill crime reporting, undermining public safety and straining local economies that rely on immigrant labor.
Other homophobic/transphobic policies or comments Mullin has backed
- Ongoing campaign to federally override trans inclusion in school sports — via multiple sessions and press pushes. Markwayne Mullin+1
- NDAA riders that limit recognition of gender identity in official DOD communications (e.g., pronoun restrictions) as part of a broader “anti-woke” agenda. Markwayne Mullin
A call to REALTORS® & RPAC (Article 10)
Article 10 of the REALTOR® Code of Ethics requires equal professional service regardless of race, color, religion, sex, handicap, familial status, national origin, sexual orientation, or gender identity. Funding candidates whose agendas erode fair-housing access, stigmatize LGBTQ families, or target immigrant communities contradicts that pledge.
Ask your REALTOR® to pause donations to RPAC until it commits to:
- Stop funding candidates advancing discriminatory laws;
- Publicly align political giving with Article 10 and fair-housing principles in practice—not only in marketing.
Fair housing isn’t partisan. Equality isn’t optional.
