"In the weeks before Trump took office, Obama administration officials were so concerned by the Trump transition team’s handling of classified documents that they moved swiftly to exert more control over the sensitive materials, according to two former U.S. officials. The officials said transition officials removed classified materials from secure rooms and carried them between buildings in Washington without permission. Worried about keeping tabs on the highly sensitive material, the Obama administration officials set new limits on some classified information and explicitly barred Trump aides from viewing that material in their transition offices. The Associated Press previously reported on Obama officials’ concerns about the transition team’s handling of classified material as the Trump team prepared to take the reins of government. The new details about their concerns come amid mounting questions about whether Trump himself has been careless with the nation’s secrets."
