I still don't understand. They knew in 2013. What exactly does "in response to revelations" mean then? What was the revelation? They've known. That sentences is bullshit and misleading at best.
> Senior members of the administration were aware of gifts the Media Lab received between 2013 and 2017 ... They knew in general terms about Epstein’s history – that he had been convicted and had served a sentence
So it would stand to reason that Reif knew about the relationship with Epstein, dating back to at least 2012.
Epstein brought Bill Gates's money through the door. Don't pretend the administration was unaware of his donation history, or that he was just some everyday small-potatoes donor.
Reif had his eyes open, he said thank you for the money, and now he's throwing others under the bus to preserve his own career.
