I have a theory which may or may not be true. During her
Benghazi testimony; she wore dark-framed big old glasses.
Now, maybe she needed them for reading glasses; but I have
an idea that she wanted to give an impression of being a
totally different person during that grilling than she likes
to try to project today.
If I recall correctly, Hillary’s Benghazi testimony was given a few weeks after she ‘fell’ down in Dec 2012. She was then suffering from double vision and other ailments. Do an internet search and you can discern the prismatic lenses in those dark-framed glasses.
