The Justice Department is reviewing the discovery of classified documents held by Joe Biden since the end of his vice presidency in 2017 in at least two locations, including one of his Delaware homes, Attorney General Merrick Garland confirmed Thursday. The first set of documents were found in November in a vacant office space at the Penn Biden Center in Washington, D.C. The second set was found more recently in a garage at Biden’s home in Wilmington.

Garland said he has appointed former U.S. attorney Robert Hur as special counsel to review the storage of the documents. Following his appointment, Hur said in a statement, “I will conduct the assigned investigation with fair, impartial, and dispassionate judgment.”
