While outside of government, Blinken served as managing director of the Penn Biden Center for Diplomacy and Global Engagement, which was affiliated with the University of Pennsylvania but located in Washington.

"Just as you heard from President Biden about a week ago I was surprised to learn that there were any government records taken to the Penn Biden Center. I had no knowledge of it at the time," Blinken said when asked about the documents, adding he would cooperate fully with a Justice Department review.
