It would be nice to see the transcript and see who is lying or not, and whether the media is just trying to make trouble.
If the Russian guy brought it up and Flynn said the Trump administration would look at it when they got into office, then a person could say either thing - that he did discuss it, or that he didn’t - without lying. The subject came up and he said it would be looked at at the proper time. What else was he supposed to do/say, if the other guy brought it up?
At this point I think we need to see the transcript, to know what’s really going on here.
That’s why “possibly” is the right answer.
AND if that’s what the “discussion” turned out to be, then the leak of this is sheer poison and the one who did it needs to go to Gitmo for a long time.
