Classified documents found at former US Vice President Pence's home

US media say documents marked as classified have been found at former Vice President Mike Pence's Indiana home.

CNN and other outlets reported that a lawyer for Pence had discovered about a dozen classified documents last week. Pence served as vice president under former President Donald Trump.

Reports say the lawyer contacted the National Archives and the materials have been handed over to the FBI. No details about the documents have been released.

The Justice Department is already looking into the discovery of classified documents at President Joe Biden's home and private office as well as Trump's residence. The department have appointed special counsels to conduct the investigations.

Pence's lawyer said in a letter to the National Archives that the former vice president had engaged outside counsel to review records stored in his home. The letter said this was done "out of abundance of caution" following reports about the finding of documents at Biden's home.

The lawyer said Pence had been unaware of the existence of sensitive or classified documents at his personal residence. He added Pence stands ready to cooperate with any appropriate inquiry.
