After the White House suspended $175 million of the University of Pennsylvania’s federal funding last week over the participation of a transgender athlete on the school’s swim team, the funding cut’s legal basis remains murky — and Harvard could be next on the list.

A social media post from the White House says Penn is losing millions of dollars in federal funding, but the university says it has received no formal notice.

Republicans in the Pennsylvania Senate on Wednesday advanced a bill that would restrict the participation of transgender student athletes in sports, setting up a vote before the full Senate.

The Trump administration gave Maine an ultimatum to ban transgender athletes from girls sports by Thursday, and state school officials appear to have defied it.
