WASHINGTON—The discovery of classified documents in an office used by President Biden after he left the vice presidency has brought attention, and House Republican scrutiny, to a little-known Washington think tank where Mr. Biden had set up operations in between his posts in the White House.
The Penn Biden Center for Diplomacy and Global Engagement, located in a building with a commanding view of the U.S. Capitol, was a key element of Mr. Biden’s initial plans for his post-government career, sketched out in part by his son, Hunter Biden .
The elder Mr. Biden and university leaders envisioned it as a place to convene foreign-policy thinkers, spur debates on global affairs, develop leaders and plan speeches and events, according to their public remarks.
