Breaking Wednesday, aides to President Joe Biden found “at least” another “batch” of classified documents. Even worse, the additional batch was found in yet a second location. Just how many places has President Joe Biden discarded classified documents?

The President himself announced it was a “surprise” to him that these documents were found at all. Nonetheless, NBC News reported the additional classified documents were unearthed and Biden aides have been looking “for more confidential records in other locations he used after approximately ten documents from Biden’s vice presidency were found at the Penn Biden Center.”

The second, separate location is different from the Washington office Biden used during the Obama administration, according to a source familiar with the matter. NBC News reports:

The classification level, number and precise location of the additional documents was not immediately clear. It also was not immediately clear when the additional documents were discovered and if the search for any other classified materials Biden may have from the Obama administration is complete.

Biden aides have been sifting through documents stored at locations beyond his former Washington office to determine if there are any other classified documents that need to be turned over to the National Archives and reviewed by the Justice Department, the person familiar with the matter said.

The search was described as exhaustive, with the goal of getting a full accounting of all classified documents that may have inadvertently been packed in boxes when Biden cleared out of the vice president’s office space in January 2017.
