I doubt the chair was a joke as she’s very demanding. She expects to be treated like a queen and asks for all sorts of niceties around her. Something like Babs Streisand expecting rose petals in her toilet.
The Las Vegas Review Journal has published articles on the demands of Hillary during her visits. I remember a couple of them. Hotel maids and others were instructed to avoid eye contact and speaking to her. It was also reported that she traveled with her own special Port-a-potty. The same was true of Barbara Streisand visits. Our founding fathers rejected any American royalty with good reason. We should do the same for such as politicians, media darlings, etc.
