Aides to President Joe Biden have found a second batch of documents, some of which may be classified, at a new location that Biden was known to use after leaving office as vice president, ABC News has learned.

Sources familiar with the White House efforts tell ABC News that the second batch of documents contained information suggesting they may be classified. The materials came to light as Biden aides conducted a search of other locations where he worked after leaving the Obama administration.

These documents came to light as Biden aides responded to the November discovery of classified documents at the Washington, D.C., office of the University of Pennsylvania’s Penn Biden Center, which Biden used after his time as vice president.
