Trump and Melania attended Game 5 of the World Series on the night of Sunday, October 27, 2019, and he was seriously boo’d. Just watch the video. The first view is great because it shows the crowd cheering, then when trump appears, the quickly starting booing.
There were chants of "Lock him up!" and "Impeach Trump" but I it’s difficult to hear in the video. Interesting how they’re all laughing it off – but what other reaction could they have displayed? After the game, I imagine trump went back to the White House to sulk. Since there were no tweets that night, I wonder if he was sucking his thumb while sulking?
