She laughs because she is part of the government "elite". Stuff like this doesn't bother her. Wouldn't be surprised she doesn't pay for her gas. But even if she does she makes way, way more than the average American.
She laughs because she knows it's true. biden f**ked up. So she laughs it off and say stupid dumb-ass things like the subject is a common occurrence that she deals with every day.
She laughs because people with cushy jobs like hers are simply out of touch with mainstream America. She is more concerned with where her next hoity toity luncheon will be with the Washington DC elite than worry about the skyrocketing prices of fuel.
She laughs, because just like kamala harris, the country's VP joke, her knowledge and expertise in issues like these are non-existant.
Yeah, go ahead and laugh, arrogant bitch. Your time of reckoning is near.

(now it's my turn to laugh....)
