Ex-Michigan State president Lou Anna Simon has been charged with lying to cops to cover up the Larry Nassar scandal ... and now she's facing years behind bars.
The ex-prez has been charged with 2 felony and 2 misdemeanor counts after an investigation determined she lied about knowing of complaints against Nassar in 2014.
According to court docs, the felony counts carry up to 4 years in prison and the misdemeanors up to 2 years.
In the docs, Simon said she was aware of a review of allegations against a sports doctor, but didn't reveal she knew it was Nassar.
Simon resigned from her position in January ... shortly after Nassar was sentenced to up to 175 years in prison for sexual abuse.
This is the 3rd school official charged as a result of the investigation into the Nassar scandal ... the school's former dean of Osteopathic Medicine, William Strampel, and ex-gymnastics coach Kathie Klages were also charged.
