"Brian Karem, a political analyst for CNN..."
Karem made a tweet, what he thought was happening - it doesn't say he said that on CNN, but I agree with him Trump was likely not there. I think he was in Florida and lying about where he was since he especially said he was alone in the White House. That is likely what he did and laughed about the fact he could lie where he was and get away with it. I heard he again today say he was alone in the White House - yes, he brought it up again so he could laugh at the stupid citizens who believe everything he says. When he keeps repeating something, he is lying and laughing inside himself.
Trump is the biggest fake news provider as he lies every day.
