Why would he be in a hospital? A hospital is a terrible place to be when you’re sick. Unless he needs a level of care that can’t be provided at the white house (unlikely) he should definitely be at the White House.
I’m not an expert, but I have to assume the White House has some pretty darn good medical equipment.
Edit: I remember from the Boris Johnson COVID-19 watch, there was some pretty…conflicting reporting. I’d take everything we see in the next few days with a gigantic chunk of rock salt.
My current wild-ass speculation is that Trump’s team has convinced him that he can get a bunch of people to give him sympathy if he lays low and plays this up a bit, especially after a pretty tough week of polling. He loves attention, so I’m guessing this is the 74 year old narcissist version of vaguebooking “on my way to the hospital now…”.
I’m really glad for stuff like that maddow tweet because in 3 months when they start whining that liberals celebrated trump getting covid, we can just link tweets like those.
