The Trump administration is giving Maine 10 days to change its policy allowing transgender athletes to compete in women’s sports, or risk legal action.

The U.S. Department of Health and Human Services (HHS) Office for Civil Rights (OCR) announced Monday that the Maine Department of Education, the Maine Principals’ Association, and Greely High School are each in violation of Title IX.

The federal agency says the three entities can resolve their violation by submitting a signed agreement or risk referral to the U.S. Department of Justice for “appropriate action.”

A Greely High School transgender athlete won a girl’s sports event in February, which drew national attention after being shared on social media by a Republican state representative.

A statement released by HHS Monday said a compliance review of the Maine Department of Education was initiated on February 21 and then expanded to include the Maine Principals’ Association and Greely High School on March 5.

It said the compliance review examined whether Maine engaged in discrimination on the basis of sex in violation of Federal law by allowing males to compete in sports reserved for girls. The review concluded three entities violated Title IX and are obligated to comply with Title IX.

“The Maine Department of Education may not shirk its obligations under Federal law by ceding control of its extracurricular activities, programs, and services to the Maine Principals’ Association,” said Anthony Archeval, Acting Director of the Office for Civil Rights at HHS. “We hope the Maine Department of Education, the Maine Principals’ Association, and Greely High School will work with us to come to an agreement that restores fairness in women’s sports.”

Republican state representative Laural Libby was censured by the Democratically led Maine House for sharing the image and first name of the high school transgender athlete on social media. The post drew national attention after it was shared.

President Trump and Maine Governor Janet Mills also engaged in a heated conversation at a White House event over Maine’s transgender athlete policy.

The statement from HHS Monday said President Trump’s Executive Order on Keeping Men Out of Women’s Sports articulates United States policy, consistent with Title IX, to protect female student athletes, in the women’s category, from having “to compete with or against or having to appear unclothed before males.”

The Maine Principals’ Association says its policy allowing transgender athletes is based on the Maine Human Rights Act, which recognizes the rights of students to participate in extracurricular activities without discrimination based on sex, sexual orientation or gender identity.
