(Sounds like they are creating an environment to assassinate Trump. They are making sure there are NO live witnesses at all in there.)
Sounds like a strong possibility. His security needs to check the water bottle they’ll give him and check the adjustable mic handle for possible poison.
I know one thing, if his side is not allowed to record every minute of it from start to finish as evidence to defend himself he should not do it. He needs evidence to refute their crooked manipulation of the content.
As someone said, they are pulling bait and switch rules at the last minute. This is a just reason to back out now. But... They might be doing all this in hopes Trump will back out first because Biden might not even be planning to actually show up.
I have been skeptical and suspect of a bluff since the beginning because they really might not want Biden to actually do this debate.
