A lawsuit appears to be the first challenge to the constitutionality of an executive order barring trans athletes from girls’ and women’s sports teams.

Two transgender teen athletes in New Hampshire have added the Trump administration to a lawsuit after the president signed an executive order banning trans athletes from women's sports.

President Trump signed an executive order on Wednesday aimed at prohibiting transgender women and girls from competing in women’s sports, directing agencies to withdraw federal funding for any schools that refused to comply. “From now on, women’s sports will be only for women,” he said in the East Room of the White House before signing the order.

The teenage plaintiffs argue Trump's latest executive order keeps transgender youth from participating in sports.
