In case you had any doubts before, this Presidency is a total joke. That's true even if they leave out the rectal exam.
On the other hand, the fact that it will be "broadcast exclusively by Fox News" all but guarantees that it won't actually be live. I bet it will be prerecorded (and heavily edited) to make sure the Dear Leader doesn't accidentally show any "signs of weakness," like accidentally giving another sign of dementia or showing just how sick he is.
