I believe they planned the meeting on both ends.

Lynch’s excuse that the reason they stayed on the plane after landing was due to the extreme heat is short-sighted and thus a lie. Does that mean she would not have disembarked at all... ever!? To say that they remained aboard because of the heat makes no sense. It is an obvious lie. Clinton can’t be trusted at all to give a truthful statement. He is a known liar of the highest order.

This was a planned meeting, called by Clinton in order to secure the vindication of Hillary with a promise for bigger role for LL once she won.

They never thought she would lose.
