Search of a politician's home
The publication specifies that FBI officials are checking to see if Pence still has classified material at home. The search is being conducted with the consent of the former vice president.
CNN's sources say that secret documents were discovered at Pence's house in late January by his lawyer. The materials were then turned over to the FBI.
In January, it also became known that a batch of classified documents had been found in the building of a Washington think-tank affiliated with incumbent US President Joe Biden, opened with the support of the University of Pennsylvania. They date back to when Biden was vice-president of the United States.
According to the White House, the papers were discovered by lawyers for the head of state in November 2022. The documents were in an office space used by Biden from 2017 to 2019 before he announced his candidacy for the presidential election. Secret papers were later found at Biden's home in Wilmington.
In a similar situation to the discovery of official documents from the former US president, the FBI retrieved hundreds of documents from Trump's Florida residence last August after he failed to comply with a subpoena to hand over classified material. Trump had more than 300 classified documents at Mar-a-Lago, which were turned over to the archive and retrieved by the FBI.
However, a spokesman for Mr Pence did not immediately respond to a request for comment. The Justice Department also did not immediately respond to a request for comment.
