K. T. McFarland served on the presidential transition team before becoming the White House deputy national security adviser.

An email exchange obtained by The New York Times indicates that Ms. McFarland was aware at the time of a crucial Dec. 29 phone call between Mr. Flynn and Mr. Kislyak that was intercepted by American intelligence.

But in testimony before Congress, she said she was unaware about Team Trump’s interactions with the Russians.

What's the penalty for lying to Congress? Hmmm.
