The  U.S. Department of Education is informing its Maine counterpart that it’s in violation of federal law by allowing transgender athletes to compete in girls’ sports.

The federal agency sent a letter Wednesday, notifying Maine’s Department of Education it’s violating Title IX, which prohibits discrimination based on sex.

The U.S. Department, under the Trump administration, first announced an investigation of Maine’s transgender sports policy on February 21st.

It’s now giving the Maine Education Department 10 days to comply with Title IV  or risk legal action through the U.S. Department of Justice and the loss of federal funding.

“The outcome of OCR’s investigation of MDOE confirms that it has violated federal antidiscrimination law by allowing boys to compete in girls’ sports and boys to occupy girls’ intimate facilities,” said Acting Assistant Secretary for Civil Rights Craig Trainor in a statement. “If Maine does not swiftly and completely come into compliance with Title IX, we will initiate the process to limit MDOE’s access to federal funding.”

Maine currently receives more than $280 million in funding from the U.S. Department of Education.

The Wednesday announcement from the U.S. Education Department came two days after the U.S. Department of Health and Human Services (HHS), a separate agency, expanded its notice of violation of Title IX from the Maine Department of Education to include both the Maine Principals’ Association, the state organization that governs high school athletics, and Greely High School in Cumberland, where a transgender athlete recently won a girls sports event.

The HHS announcement also gave the Maine entities 10 days to fall in compliance.

Meanwhile, the Maine Principals’ Association is challenging its inclusion in the HHS claim that it’s violating Title IV.

An attorney for the Association sent a letter Wednesday to HHS, which pointed out that it does not receive any federal funding, and therefore, is not required to comply with Title IV.

The letter says the HHS must dismiss its compliance review of the Principals’ Association because it lacks jurisdiction.

The Trump administration has been targeting Maine for its transgender sports policy since a White House meeting in February that included a heated conversation between President Donald Trump and Governor Janet Mills.
