Michael Flynn reportedly plans to invoke his Fifth Amendment right against self-incrimination on Monday. The letter went on to say the Justice Department's recent appointment of a special counsel has created a legally unsafe environment for him to cooperate with the panel's investigation.
Flynn's decision, which his attorneys announced in a letter sent Monday to committee chairman Richard Burr, R-North Carolina, and vice chairman Mark Warner, D-Virginia, comes as evidence continues to mount elsewhere in Congress that the former national security adviser appears to have misrepresented his Russian Federation ties. Earlier this month, the committee asked Flynn and other Trump associates for lists of meetings and notes taken during the presidential campaign. Flynn's legal team said he was rejecting the subpoena because the committee spurned his offer, made in a May 8 letter, "to give a full account of the facts and to answer the committee's questions, should the circumstances permit, including assurances against unfair prosecution".
Flynn, who resigned this year as President Trump's national security adviser, told investigators in February 2016 that he had received no income from foreign companies and had only "insubstantial contact" with foreign nationals, according to the letter.
"The context in which the committee has called for General Flynn's testimonial production of documents makes clear that he has more than a reasonable apprehension that any testimony he provides could be used against him", the lawyers wrote in a letter to the heads of the committee informing them Flynn would invoke his Fifth Amendment right against self-incrimination.
Ms Ginsberg also noted that the committee faces new complications from the Justice Department's move last week to appoint Mr Mueller as special counsel in the Russian Federation inquiry.
His attorney, Robert Kelner, declined to comment on the new assertions by Cummings.

Flynn's refusal to testify without an immunity grant represents an apparent reversal of his views toward the legal procedure.
Sen. Richard Burr (R-NC), chairman of the Senate Select Committee on Intelligence, and Sen. He'd informed the committee last week that Flynn would not respond to the subpoena.
Flynn's former boss has also discounted immunity deals.
Comey was sacked by Trump earlier this month.
Also Monday, Rep. Elijah Cummings, D-Md., said documents already in the House Oversight Committee's possession appear to indicate that Flynn may have lied to investigators previous year when they were conducting a background check for his top-level security clearance.
The top Democrat on one of those congressional probes, Rep. Elijah E. Cummings, said Monday he has evidence that Mr. Flynn lied in his security clearance process in early 2016.
"He is the target on almost a daily basis of outrageous allegations, often attributed to anonymous sources in Congress", the letter stated, decrying an "escalating public frenzy against him".
