 In Michigan, the first campaign rally featuring Republican nominee Donald Trump and his running mate, J.D. Vance, is underway. Senator Vance took the stage early, and he's talking about national security. There's nothing radical about having a strong national security, that when we go to war, we punch and we punch hard, but being cautious and not trying to get America involved in every far-flung corner and conflict of the world. Sometimes, my friends, it just is none of our business.
