Former Vice President Joe Biden and other top Obama officials received information in response to “unmasking” requests targeting retired Lt. Gen. Michael Flynn in the final weeks of the previous administration, according to a memo declassified by acting Director of National Intelligence Richard Grenell.

The list, obtained by the Washington Examiner on Wednesday, shows Biden received information at least once in response to such an unmasking request on Jan. 12, 2017, but it is not clear whether he made the request or even looked at the information. Biden is now the presumptive Democratic presidential nominee in the 2020 contest for the White House.

The newly declassified records show that 16 individuals made unmasking requests related to the incoming Trump national security adviser, and the list shows which officials received that sensitive information. It was not immediately clear which individuals made the requests, but those who received the unmasking information were laid out chronologically.
