"For nearly 50 years, Title IX has represented an American commitment to provide women with equal opportunities in educational programs and activities. Today, the Biden administration is intent on erasing the contributions made by women and changing the world of athletics as we know it," Blackburn said in a news release. "Now more than ever, it’s important to celebrate girls and women in sports, and I’m glad to champion this resolution in their honor."

More than 20 Republican senators co-sponsored the resolution.

It also received support from former NCAA champion swimmer Riley Gaines, Olympic gold medalist Caitlyn Jenner, former ESPN anchor Sage Steele, the Independent Women’s Forum and other groups.

"It’s because of brave Tennessee women like Sen. Blackburn, Wilma Rudolph and Pat Head Summitt that women can serve and compete at the highest levels. I can’t wait to celebrate real women on XX day," said Gaines, an OutKick contributor who hosts the "Gaines for Girls" podcast.

"As the world's greatest athlete, with an international platform reaching millions, it is my privilege to use my voice to advocate on the simple common sense issue of fairness in sports for women and girls," Jenner, a Fox News contributor, wrote. 

"Moreover, as a parent and grandparent of numerous daughters and granddaughters, I personally find it more important than ever to stand up to the radical lefts attacks on hard fought protections found in Title IX. I witnessed firsthand the fight for these protections for women and girls in the 70's, at the height of my athletic career. It is critical at a time such as this all of us unite around common sense and emphasize the asize the importance of American women and girls in sports!" 

"As a longtime sportscaster and champion of women’s sports, I am appalled and disgusted with the Biden administration’s decision to tear apart Title IX after more than 50 years of progress," Steele added. "Therefore, I am honored to stand alongside Senator Marsha Blackburn as she chooses to fight back and celebrate women and girls. I am so grateful for her commitment, and I will personally do everything in my power to forever protect, uplift and celebrate women and girls! Can’t wait until October 10th!"

Gaines on Tuesday called Biden’s overhaul of Title IX the "most anti-woman" pursuit of this administration. Speaking at a virtual press conference attended by Tennessee Attorney General Jonathan Skrmetti and West Virginia Attorney General Patrick Morrisey, Gaines spoke at length about the overhaul which aims at safeguarding LGBTQ+ students and changing the ways in which sexual harassment and assault claims are adjudicated on campus.

While the administration’s new rules broadly protect against discrimination based on sex, they do not offer guidance about transgender athletes, but many Republican states argue that they could be interpreted as such.
