I don’t think the real oval office is set up to have the giant flatscreen TV type of Teleprompter that Biden uses in the fake Oval Office. All the reporters who go in that room know exactly what Biden is doing, reading everything. Not one of them mentions it but every once in a while a cameraman messes up and shows part of that big screen

I know when I had a relative with Alzheimer’s Who had to be in a nursing home, they have special sections where everything from colors to the type of lighting used was done specifically to make it easier on the patients and make them feel more at home, if you will.
