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.

The Ivy League schools collectively received an astonishing $6.4 billion in federal funding during the fiscal year 2024. For instance, the University of Pennsylvania alone was allotted approximately $1.

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.
