Michigan U.S. Sens. Gary Peters and Debbie Stabenow have now joined the calls for Michigan State University President Lou Anna K. Simon to resign.

In a statement, Peters said the survivors who have come forward throughout ex-MSU doctor Larry Nassar's sentencing hearing "have fully awoken us to the evil he perpetrated, and now the judicial system has delivered the justice it can provide."

"However, it has become clear that the leadership at Michigan State University has failed to adequately prevent, address or respond to the victimization of young women and girls on its campus, and the crisis at MSU continues despite today's verdict," he said.

Peters said MSU has a long way to go in terms of rebuilding trust with its community, as well as the entire state of Michigan. To do that, new leadership is in order.

"As an MSU alumnus, I add my voice to those calling for President Simon's resignation, and I will work in the U.S. Senate to address the failures that led us to this day," Peters said.

On Twitter, Stabenow said "it's clear that it's in the best interests of these courageous survivors, their families and our state for President Lou Anna Simon to resign."

The calls from Michigan's U.S. Senators come as victims of Nassar, state politicians, members of the public and two members of the MSU Board of Trustees have insisted a change in leadership is necessary.

Also Wednesday, MSU Trustee Dianne Byrum became the second member of the board to call for Simon's resignation.
