Five more pages of classified documents have been found at US President Joe Biden's home in Delaware.
The White House noted the discovery in a statement Saturday. The Justice Department had already appointed a special counsel to investigate Biden's handling of classified files based on previous finds of such items at his home and private office.
The classified documents are from the time when Biden was vice president under President Barack Obama.
The White House says that all the documents have been handed to the Justice Department.
The first such classified items were found in November last year before the mid-term election. The Biden administration didn't comment on the matter immediately, waiting until after news media reported the discovery.
White House Press Secretary Karine Jean-Pierre has said the administration will continue to cooperate with the probe.
