Former national security adviser Susan Rice privately told House investigators that she unmasked the identities of senior Trump officials to understand why the crown prince of the United Arab Emirates was in New York late last year, multiple sources told CNN.

The New York meeting preceded a separate effort by the UAE to facilitate a back-channel communication between Russia and the incoming Trump White House.

The crown prince, Sheikh Mohammed bin Zayed al-Nahyan, arrived in New York last December in the transition period before Trump was sworn into office for a meeting with several top Trump officials, including Michael Flynn, the president’s son-in-law, Jared Kushner, and his top strategist Steve Bannon, sources said.
