Here is an example. It's a fairly quiet end to a week that started with lots of speculation about the Mueller report and Trump firing his secretary of Homeland Security and other related positions. So what is the top news today?
Trump Wants to Bus Migrants to Sanctuary Cities
This is why I think it's a fake story: it's on a buzzy issue. It's a slap in the face of one of his favorite enemies. It's not an acutal policy announcement, but it looks like an action. (It won't be. Announce first, worry about planning later.) If you think about it hard, you realize it's probably not at all likely to happen. He didn't deliver it in a written speech in front of a teleprompter (that indicated more serious announcements).
Sometimes Trump will grab the newscycle just is an outrageous claim or insult. I'll try to remember to add some examples. But it's the same sort of tactic. Be outrageous, capture the newscycle, don't worry because few will remember.
If I was in the news biz, I'd have a weekly column about the crazy stuff Trump had done. I wouldn't give him a headline for something like this. Instead, I'd put it on the weekly list and save it for Saturday or Sunday:
