Flynn: Senior Member Of Trump Team Told Me To Contact Russia Over UN Vote

Flynn entered the plea at a federal court in Washington, D.C., shortly after Special Counsel Robert Mueller's office released a one-count charging document.

The false-statements charge pertains to Flynn's interactions with the Russian ambassador in late December -- specifically discussions about sanctions and other matters he apparently claimed never happened.

Flynn, a retired Army lieutenant general, becomes the first Trump ex-White House official to face charges in the probe.
