President Joe Biden's legal team has reportedly found a new batch of classified documents in a new location.

People familiar with the matter told CNN on Wednesday that searches for more classified documents happened after Biden's attorneys found the initial batch of government records in early November.

The first batch of classified documents from Biden's time as vice president was found at his former think tank office at the University of Pennsylvania in Washington.

It is unclear at this time where the new batch of classified documents was located.

It is also being determined how many documents were in the latest set of government records or what they were about. The date when the new documents were found was also not disclosed.

A source briefed on the matter told NBC News that Biden aides have been scouring other locations aside from his former Washington office to see if there are other classified documents that need to be handed over to the National Archives and reviewed by the Justice Department.

In a statement on Monday, the White House confirmed that a "small number of documents" had been found at a Washington think tank tied to Biden during his vice presidency in Barack Obama's administration.

The chair and vice chair of the Senate intelligence committee asked for access to the classified documents. The National Archives referred the classified documents to the Justice Department.

Former President Donald Trump has repeatedly slammed Biden on his Truth Social app regarding the discovery of the classified documents.

Joe Biden Classified Documents and Donald Trump Classified Documents

One of the differences between Joe Biden's and Donald Trump's cases of classified documents was how it was returned or handed over to the National Archives.

Archives contacted Trump officials soon after he left office in 2021, informing him that the agency believed some of the documents were missing and requesting their return.

Court paper showed officials found 14 out of 15 boxes containing classified documents from Trump's Mar-a-Lago estate.

There were 184 documents marked classified in the boxes, with many more found later on. On the other hand, Biden's classified documents were immediately handed over to National Archives upon discovery. 

The agency was unaware of the missing documents and had not made any request to the president for their return.

The Federal Bureau of Investigation (FBI) learned that Trump had not fully complied with the subpoena for the return of the documents, leading to the search of the former president's Mar-a-Lago property.

A source familiar with the matter said Biden only became aware of the classified documents in his former office when his lawyers told him they had discovered them.

Joe Biden on Classified Documents

Joe Biden said he was surprised to learn about the classified files found at his former private office.

He noted that he did not know what was in the documents, indicating that his lawyers had advised him not to ask about the contents of the materials.

A source familiar with the matter told CNN that the items discovered in Biden's former private office include 10 classified documents, including U.S. intelligence memos and briefing materials covering topics such as Iran, Ukraine, and the United Kingdom.

The Justice Department is currently looking into the matter. A Republican congressional committee noted that it will also investigate. 

GOP congressman James Comer, chairman of the House Oversight Committee, expressed concerns that Biden "compromised" intelligence sources. 

He asked the White House to turn over its documents and communications concerning the classified materials.

Another insider told CNN that Attorney General Merrick Garland has already asked John Lausch Jr., the U.S. attorney in Chicago, to review the matter.

The source noted that Lausch has completed the initial part of his inquiry and has already submitted his preliminary findings to Garland, who is now facing a critical decision on how to proceed, including whether to open a full-blown criminal probe or not.
