Tammy had noted the First Lady’s belt looked like a hose clamp, but I found it reminiscent of a suicide belt. I wouldn’t read too much into this goofy observation; I really don’t worry overmuch about what the Washington bozos look like. But that’s the image that came to mind.
As you can see, suicide belts are becoming quite haut fashion these days.
