Public = television interview, radio interview
newspaper interview, on the 6 o'clock news, etc. Since, so far, the only place that I can find his "apology" is on his website, it goed directly to the (lack of) character of the man.
Question: Why didn't he say this when he did the interview, on his local Fox News no less, the morning after? Did he need his PR manager to smack him upside the head to give him a clue?
"Chicago to my mind was the only place to be. ... I above all liked the city because it was filled with people all a-bustle, and the clatter of hooves and carriages, and with delivery wagons and drays and peddlers and the boom and clank of freight trains. And when those black clouds came sailing in from the west, pouring thunderstorms upon us so that you couldn't hear the cries or curses of humankind, I liked that best of all. Chicago could stand up to the worst God had to offer. I understood why it was built--a place for trade, of course, with railroads and ships and so on, but mostly to give all of us a magnitude of defiance that is not provided by one house on the plains. And the plains is where those storms come from."
