We've all had an uncontrollable case of the giggles before. The timing of nervous laughter isn't always appropriate. But when you are the vice president of the United States, you might want to control yourself. I don't know if this is a nervous tic from Kamala Harris. Maybe it's more of a "tell" when she is hiding something. I'd love to play poker with her one day. You could ask her if she's bluffing, then watch her say "no" while she squirts milk out of her nose trying to contain her laughter. Whatever Harris' excuse is, laughing about visiting the border that's in crisis because of your boss' policies is less than appropriate.
