First on CNN: Classified documents found at Pence's Indiana home - CNN

The FBI and the Justice Department’s National Security Division have launched a review of the documents and how they ended up in Pence’s house in Indiana.

Sources said that the attorney, Matt Morgan, began going through four boxes stored at Pence’s house last week, finding a small number of documents with classified markings.

On Monday, Pence’s legal team drove the boxes back to Washington, DC, and handed them over to the Archives to review the rest of the material for compliance with the Presidential Records Act.

“Vice President Pence understands the high importance of protecting sensitive and classified information and stands ready and willing to cooperate fully with the National Archives and any appropriate inquiry.”

Federal investigators took that step because they believed Trump had not turned over all classified material despite a subpoena and were concerned records at Mar-a-Lago were being moved around.

“He has agreed to fully cooperate with congressional oversight and any questions we have about the matter,” said Comer, adding that Pence’s transparency “stands in stark contrast” to the Biden administration’s response to Congress over the classified documents.
