The guy nods at Holt, but I did not see anything change hands.
Stop searching for conspiracies. There is enough to hate her over. This type of junk will just take years off of your life.
I despise conspiracy types as well. . .but I see the guy approaching Holt and switching hands as they approach each other for what appears to me like a hand-off was in progress. And why would Holt make a bee-line to the back of the stage instead of a) stay and chat with well-wishers and such as been done by previous moderators, or b) depart stage left or right, as that is how he entered the debate arena.

There is reasonable doubt that if this were a court case, she would be guilty of cheating.
