I think the first tweet is a good argument. I personally think second tweet is not only a stretch it's the exact kind of tweet POTUS should have been using Twitter. He just says, in a normal manner, "I won't attend X" without SHOUTING or using weird adjectives like "nasty woman" or whatever.

I think it's important to understand that Twitter needs to be very conservative here. All social media banned Trump, and twitter really is the last place his voice can be heard (via a famous privately-owned social media organ). Well, if Trump tweets "I'm gonna nuke Iran" tomorrow they don't want to be the place Trump announces this.
