The date falls several weeks after the Nov. 6 mid-term elections.

Flynn has been cooperating with the Mueller probe after pleading guilty on Dec. 1, 2017 to a charge of making two false statements to the FBI about his interactions with then Russian Ambassador Sergey Kislyak after the 2016 U.S. elections and before Trump's inauguration in January 2017.

The retired lieutenant general is the first senior White House official to be charged in Mueller's probe.
