1) There is one other theory on the ChinFein senator. She could have had to put her hand up there to hold herself up. She IS 85 years old. Altho she looks pretty spry.

No sale.   Her whole posture and demeanor is one of domination and intimidation.   Without words she's saying to LM "You do as you're told or else!"  Notice LM's in a little alcove/doorway, cornered.
