EXCLUSIVE: Sen. Tommy Tuberville, R-Ala., sharply criticized President Biden’s proposed Title IX rules in a letter to Secretary of Education Miguel Cardona, calling the interpretation "misguided" and causing "irreparable harm to women." 

The Department of Education's proposed rules would expand Title IX’s protections to include sexual orientation and gender identity, drawing harsh criticism from opponents who believe it would harm women’s rights.

"This proposed rule is a monumental setback for the generations of women who have benefited from Title IX’s enactment over the last fifty years. The Department should not move forward with this proposed rule, but instead, work with Congress on legislative action meant to strengthen the protections afforded women in the original statute," Tuberville said in the letter.

While the Department of Education plans to release a separate rule related to Title IX and sports, Tuberville warned that the existing proposed changes would dramatically decrease funding for, and participation in, women's sports. 

"Being 40 years in education, I've seen a lot of great things … the opportunities that have been given to young girls and women," he told Fox News Digital, highlighting the dramatic increase in women's sports participation over the 50 years Title IX has been in existence.

"I think we're going to start losing numbers, we're going to start losing interest," Tuberville, who was a high school and college athletic coach before running for office, said. "Bottom line is, we're going to take something that has been very, very successful and make it average." 

"It's an attack on women, and it's an attack on young girls," Tuberville warned. "You're defeating the idea of giving girls and women the opportunity to have their own sports, to compete into their own sports."

Title IX, which was passed into law in 1972, prohibited sex-based discrimination in schools that receive federal funding. It stated that "No person in the United States shall, on the basis of sex, be excluded from participation in, be denied the benefits of, or be subjected to discrimination under any education program or activity receiving Federal financial assistance."

"This proposed rule reverts the playing field to a time before Title IX’s enactment and will cause irreparable harm to women entering academia in the future," Tuberville’s letter said.
