May 18 (UPI) -- Ousted national security adviser Michael Flynn may not cooperate with the U.S. Senate's investigation into reputed Russian electoral interference, a top congressional Republican said Thursday.
Senate Intelligence Committee Chairman Richard Burr told news media late Thursday morning that Flynn's attorneys told him the former adviser won't obey a subpoena to cooperate as part of the panel's Russia probe.
Flynn, among others, is a primary focus of three simultaneous U.S. investigations into the matter.
"Flynn's lawyers said he would not honor the subpoena, and that's not a surprise to the committee," the North Carolina senator and chair of the committee said. "But we will figure out on Gen. Flynn what the next step, if any, is."
The former top national security adviser to the Trump White House was forced out of the position in February after it became known that he did not disclose contact he'd had with Russian diplomat Sergei Kislyak to Vice President Mike Pence.
Since his ouster, Flynn has been one of the central figures in the case addressing potential collusion between the Kremlin and President Donald Trump's campaign.
Burr noted later Thursday, though, that it's possible Flynn has not yet definitively decided whether he will comply with the subpoena or not.
"We are continuing on with a lot of interviews and through those interviews it leads us to additional document requests and additional individuals we'd like to talk to," Burr said.
