President Donald Trump will use an executive order Wednesday to bar transgender athletes under the federal Title IX law. That law bars sex discrimination at educational institutions that receive federal funds.

In a letter to school districts, universities, and others on Jan. 31, the Education Department said it would reinstate Trump’s Title IX regulations from his first term, dropping an effort from the Biden administration to expand the rules to offer more protections to LGBTQ+ students.

The US Department of Education announced Thursday that it is launching an investigation into the MIAA for “apparent Title IX violations.”
