Harvard University has filed a lawsuit against the United States Department of Health and Human Services (HHS) and other federal agencies, challenging the Trump administration’s decision to freeze $2.

Harvard’s lawyers suggest the administration was sloppy when it froze billions in federal funding. A mundane but crucial law is essential to the university’s case against the government.

Harvard, one of the most prestigious universities in the United States, on Monday sued the Trump administration after federal funding was withdrawn and institutional oversight was demanded.
