Olympic gold medalist Caitlyn Jenner on Monday said she supported a local New York official’s order banning female sports teams with transgender athletes from using county-owned facilities.

The ban applies to over 100 athletic facilities in New York City’s Long Island suburbs. Speaking alongside Nassau County Executive Bruce Blakeman at his office in Mineola, Jenner said allowing transgender athletes like herself to compete against other women will “ruin women’s sports” for years to come.

“Let’s stop it now while we can,” said the reality television star, who came out as a transgender woman in 2015.

The LGBT Network, a Long Island-based advocacy group, called Jenner’s comments a “baffling contradiction” to her own identity as a transgender woman that is “not only hypocritical but also harmful” to the LGBTQ community.

“It is disheartening to witness someone who has experienced the challenges of being marginalized actively contribute to the oppression of others within the same community,” David Kilmnick, the group’s president, said in a statement. “Such actions only serve to amplify the voices of intolerance and detract from the collective efforts towards a more inclusive society.”

Blakeman, a Republican elected in 2021, issued an executive order in February requiring any teams, leagues or organizations seeking a permit from the county’s parks and recreation department to “expressly designate” whether they are for male, female or coed athletes.

Any teams designated as “female” would be denied permits if they allow transgender athletes to participate.

The ban doesn’t apply to men’s teams with transgender athletes. It covers all Nassau County-owned facilities, including ballfields, basketball and tennis courts, swimming pools and ice rinks.

Jenner, 74, competed against men when she won the Olympic gold medal in the decathlon in 1976. She said she has “sympathy” for LGBTQ people and “understands their struggles” but argued that allowing transgender people to compete with women would undermine gains female athletes achieved under Title IX, a law banning sex discrimination in programs that receive federal funds.

“All I’m trying to do is protect women,” Jenner said Monday.

Jenner, a supporter of former President Donald Trump, has been a vocal opponent of transgender athletes competing in women’s sports. A New York native, she has long lived in the Los Angeles area and ran unsuccessfully for California governor as a Republican in 2021.

Blakeman has argued the ban is intended to both foster fair play and protect girls and women from getting injured if they play against transgender women. His executive order, however, also covers sports like swimming, gymnastics, figure skating and track, where there is no physical contact between competitors.

The executive order also takes decisions about who can play out of the hands of leagues and gives it to the government.

The Long Island Roller Rebels, a local women’s roller derby league, asked a New York court to invalidate the county order, saying it violates the state’s anti-discrimination laws.
