Citing the Fifth Amendment right against self-incrimination, Flynn's lawyer said on Monday that Flynn would not comply with subpoenas from the Senate intelligence committee, which is conducting its own parallel investigation into Russia's interference in the election and whether it colluded with President Donald Trump's associates.
"While we disagree with Gen. Flynn's lawyer's interpretation of taking the Fifth, it is even more clear that a business does not have a right to take the Fifth if it's a corporation", said top committee Democrat Mark Warner of Virginia.

Mr Brennan said he had warned Moscow against interfering in the USA presidential election, confirming that an FBI investigation had been opened in July.
Warner, a Democrat, said that the subpoenas were issued Tuesday afternoon for Flynn Intel, LLC. and Flynn Intel, Inc., two Alexandria, Va. -based consulting firms that Flynn started after he left the Defense Intelligence Agency in 2014.

At that same hearing, former director of national intelligence James Clapper said that Moscow's leaders "must be congratulating themselves for having exceeded their wildest expectations with a minimal expenditure of resource", a reference not only to the outcome of the 2016 race but also to the chaos that has characterized the early months of the Trump administration.

Meanwhile, former Trump campaign foreign policy adviser Carter Page said he will testify next month before the House intelligence committee, and the New York Times reported that USA intelligence services obtained information during the 2016 election that showed senior Russian officials discussing how to influence Mr Trump through his advisers.
The House committee's subpoenas "will be created to maximize our chance of getting the information that we need", Schiff told reporters at a breakfast hosted by the Christian Science Monitor.
Trump, now on a nine-day global trip, has had his own conversations with the Russians questioned in light of reports that he shared extremely classified intelligence with Russian diplomats in the Oval Office on May 10.
"The substance of those briefings was entirely consistent with the main judgements contained in the January classified and unclassified assessments, namely that Russia's goals were to undermine public faith in the U.S. democratic process, denigrate Secretary Clinton and harm her electability and potential presidency, and to help President Trump's election chances", the former CIA Director said.
Brennan's testimony was the first public confirmation of the worry at high levels of the us government a year ago over suspicious contacts between Trump campaign associates and Moscow. But Burr and Warner questioned "whether you can take the Fifth, as it relates to document production".
Flynn announced a decision to step down in February after it was revealed he misled White House officials, including Vice President Mike Pence, about the extent of his talks with Russian officials.
