You bring up a point there that I have not seen many people consider: Where is Kamala Harris in all this? And from the outside it is as simple as that.
A friend in Europe said: Biden is everywhere but we never see or hear from the VP. In this time of big elections I find that odd.
Trump demanded the debate, Biden should have demanded thorough fact checks with graphs and balances.
I personally would not have stepped in any debate setting with a certified liar and scammer without any sort of fact checking, it’s just foolishness.
