I'm speculating too, of course, but based on her history, if she agrees to talk to him, that will convince me it's a setup. She won't even appear as an adored and fawned-on guest on Oprah without seeing all of the questions first--no way she'd risk making a fool of herself by participating in a real-life crisis.
My guess is that if it was scripted, guns would be involved. I’m not jumping to that conclusion. There are too many people who don’t want her to be president. There are probably more than a few of those willing to take matters into their own hands to prevent that from happening. If she takes the election (notice I said “takes”), this episode might look like a cake walk, because I anticipate there will be those who revolt. Prayers for all involved and a safe ending to this matter.
