Survivors of Larry Nassar's sexual assaults have initiated legal action against Michigan State University (MSU), alleging the institution withheld thousands of documents related to the Nassar investigation from the state attorney general. The lawsuit, filed Thursday, claims MSU officials made "secret decisions" about releasing documents and refused to disclose over 6,000 documents, including emails detailing the board of trustees' decision-making process regarding Nassar. MSU claims the documents were withheld due to attorney-client privilege. The plaintiffs, who include survivors and their parents, seek accountability rather than financial compensation.

This lawsuit follows Nassar's recent stabbing incident in prison, where he is serving a sentence of 40 to 175 years for sexually assaulting numerous young women and girls. The stabbing reportedly followed a lewd comment Nassar made while watching a tennis match. He suffered multiple stab wounds and a collapsed lung, but was reported to be in stable condition.

MSU, where Nassar was employed as a sports doctor and received his medical degree, has faced significant criticism for its handling of the Nassar investigation and its treatment of survivors. The university was fined $4.5 million by the Department of Education and paid $500 million in settlements to victims.
