An executive order issued in a New York county will ban transgender athletes from competing on girls or women’s sports leagues and teams at county facilities, effective immediately, Nassau County executive Bruce Blakeman announced Thursday.

The announcement marks the latest restriction in the United States on transgender athletes’ participation in sports based on their gender identities.

“There are men’s and boys’ leagues, there are women’s and girls’ leagues, and there are coed leagues,” Blakeman said at a Thursday news conference.

Some of the Long Island county’s facilities are used by high schools, private schools, colleges and universities, he said.

“What we are saying here today with our executive order is that if a league or team identifies themselves or advertises themselves to be a girls or women’s league or team, then biological males should not be competing in those leagues,” Blakeman said, adding transgender athletes are still allowed to compete on all-boys or coed leagues in the county.
