White House lawyers last month learned that the former national security adviser Susan Rice requested the identities of U.S. persons in raw intelligence reports on dozens of occasions that connect to the Donald Trump transition and campaign, according to U.S. officials familiar with the matter.
The pattern of Rice's requests was discovered in a National Security Council review of the government's policy on "unmasking" the identities of individuals in the U.S. who are not targets of electronic eavesdropping, but whose communications are collected incidentally. Normally those names are redacted from summaries of monitored conversations and appear in reports as something like "U.S. Person One."
The intelligence reports were summaries of monitored conversations -- primarily between foreign officials discussing the Trump transition, but also in some cases direct contact between members of the Trump team and monitored foreign officials. One U.S. official familiar with the reports said they contained valuable political information on the Trump transition such as whom the Trump team was meeting, the views of Trump associates on foreign policy matters and plans for the incoming administration.
