Rachael Denhollander, the first woman to publicly come forward with allegations against Nassar, said Strampel's behavior during the 2014 Title IX investigation of Nassar and beyond should have been a massive red flag that something was wrong in the department.

"To be honest, I'm not surprised," Denhollander said. "The fact that Strampel could have those kinds of complaints against him in his personnel file and no one did anything ... both his conduct and the responses to his conduct was a very clear signal of a deep problem at MSU."

Denhollander tweeted #MSUshameonyou along with statements from the affidavit and other details, criticizing MSU's efforts to dismiss liability in lawsuits against the university in light of the charges against Strampel.

Survivor Morgan McCaul said she'd heard rumors of Strampel harassing women before, but never realized his behavior was as bad as what he's charged with.

"I think more people knew about it than are pretending to," McCaul said.

McCaul said no attention was paid to Strampel for a long period because no one except survivors were calling to hold him accountable. MSU felt no obligation to terminate him until optics dictated otherwise, she said. The charges are a good first step in the investigation, McCaul said, but other enablers remain.

"It's unfortunate that it takes this much media attention and detriment to a school's reputation to get this sort of action," McCaul said.

On Twitter, McCaul called attention to the silence of Interim President John Engler and trustees Mitch Lyons and Brian Mosallam in wake of the charges against Strampel.

"We (knew) that William Strampel was an evil man for a long time," McCaul wrote in a tweet. "Now, everyone knows. #MeTooMSU"

Olympic gymnast Aly Raisman released a statement asking what more it will take for an independent investigation into MSU and related parties.

"Nassar's former boss at MSU, William Strampel, has been arrested. MSU, still refuse to take responsibility? Yet another painful example of continued mishandling and a stark reminder of the dangers that will remain in these organizations absent of full and independent investigation that looks into everything, not just Nassar," Raisman said on Twitter. 

Survivor Lindsey Lemke praised the action being taken against Strampel, but encouraged further investigation, asserting "Strampel is not the only enabler."

Attorney Stephen Drew, who represents several Nassar survivors in litigation, said he was surprised, but not shocked at the charges Strampel faces. 

"I've said all along and we've said it from the beginning, that predators stay where they're comfortable, predators stay where they're enabled, predators stay where there's a system that allows them to exist without accountability," Drew said. 

Lansing State Journal reporter Matt Mencarini tweeted a statement from Jamie White, one of the attorneys who represents survivors. White applauded the investigation, but called MSU "grossly negligent" in failing to investigate the matter earlier.

Engler released a statement on Strampel's arrest on Tuesday, in which he said Strampel had not acted with the level of professionalism expected of an MSU employee.

In February, Engler moved to begin revoking Strampel's tenure at MSU.

"With our action to revoke tenure, we are sending an unmistakable message that employees who do not treat students, faculty, or anyone else appropriately are subject to administrative discipline up to and including firing," Engler said in the statement.
