Joe Biden in one of his first acts as POTUS means to unemploy the current team of Secret Service putting them out of work afraid that they might be loyal to Trump.
Now Joe is afraid of his own shadow.
Maybe he thinks the Secret Service will inject him with the virus or put a pillow over his head while sleeping or maybe they'll off him out the door of Airforce One?
This is about in keeping with the paranoia of the sick old man as he plans to have the entire WH "Disinfected" top to bottom before entering.
But it is OK for YOU to be there.
If Trump had done that after Obumma leaving, he'd be denounced as a racist. In this case, our new POTUS is just a terrified little deranged kook afraid of his own shadow.
I expect Joe will wear a hood, mask and rubber gloves meeting with world leaders in separate rooms over a video link.
