WASHINGTON (Reuters) - Former White House National Security Adviser Michael Flynn has told the Senate Intelligence Committee he will begin turning over some documents subpoenaed by the panel, according to a government source familiar with the matter. Flynn’s representatives told the committee in an email on Tuesday that they would start turning over some subpoenaed documents in time to meet a deadline set by the panel, and that more documents will be turned over later. The committee, which is investigating alleged Russian interference in last year’s U.S. presidential election, issued subpoenas to two of Flynn’s businesses after Flynn had declined to comply with a subpoena issued to him personally.
