There's late word of a new wrinkle, in the Russia probe.

FOX's Jared Halpern reports from Capitol Hill:

The lawyer for former National Security Adviser Michael Flynn says he will not honor a subpoena from the Senate Intelligence Committee, requesting private documents.

The panel's Republican chairman Richard Burr announcing that to reporters, saying he's not surprised and will figure out what the next step is.

The Senate Intel Committee is one of several congressional panels investigating Russia's role in the 2016 election, including looking into whether or not there were links with President Trump's campaign.

Former FBI director Robert Mueller has been named by the Justice Department to oversee the federal investigation into that issue.
