On Thursday, The chairman of the Senate intelligence committee said National Security Adviser Michael Flynn hasn't responded to a subpoena. the panel issued the subpoena in its investigation of Russia's meddling in the 2016 presidential election.
The report, which cited two people familiar with the case, said Flynn informed the transition team's chief lawyer about the probe on January 4, much earlier than previously reported.
The Senate committee issued the subpoena for Flynn's records on May 10 after he declined to cooperate with an April 28 request for documents. "Consistent with the Committee's position since the beginning of [our] investigation, I welcome their willingness to cooperate".
The Senate Intelligence Committee's counterterrorism probe took on added significance after President Donald Trump dismissed FBI Director James Comey last week amid allegations of Russian meddling in the 2016 US presidential election.
Nina Ginsberg, a veteran Washington defense attorney with extensive experience in national security cases, said that without an ironclad immunity deal from the committee, Flynn would be exposed to questioning from investigators about any personal documents he gave up.
Flynn was ousted following reports that he misled Pence and others when he denied discussing sanctions in a phone conversation with Russian Ambassador Sergei Kislyak before Trump's inauguration.
"Michael Flynn has not cooperated with the committee up to this point", Burr said, adding, however, that he has not received a "definitive answer" on whether Flynn and his lawyers will comply.More news: U.S. airstrike hits pro-regime forces in Syria — Military official
