They probably just called this guy
There are portable x-ray machines. There are companies where that is all they do, go to pts house and do x-rays, especially CXR’s. You would do lab work as well and lab draws can be done at home and taken to a lab.
But I don’t see you doing that for a Presidential candidate unless her handlers and her were adamant that she not risk being seen in a Dr’s office our at the hospital.
And the fact that they are working so hard to cover up her health problems tells me that’s probably what happened IF she has pneumonia, which I highly doubt.
A chest X-ray is not always necessary for a pneumonia diagnosis. Any doctor worth his salt can hear pneumonia with a stethoscope if it’s at a certain stage. An X-ray can confirm it.
