The Trump administration on Tuesday declassified an email that former national security adviser (NSA) Susan Rice sent herself about a meeting discussing "sensitive information related to Russia" and her incoming successor, Michael Flynn.

"Comey said he does have some concerns that incoming NSA Flynn is speaking frequently with Russian Ambassador [Sergey] Kislyak. Comey said that could be an issue as it relates to sharing sensitive information," Rice wrote in the email, which was formerly classified as "top secret."


"President Obama asked if Comey was saying that the NSC [National Security Council] should not pass sensitive information related to Russia to Flynn. Comey replied 'potentially,'" she continued. "He added that he has no indication thus far that Flynn has passed classified information to Kislyak, but he noted that 'the level of communication is unusual.'"
