Trump left Cleveland during the convention?

Did I hear that correctly that his message to the RNC was from Trump Tower?

So he is flying back and forth? (Pay attention donators - you have just paid for his flights back and forth.) But the delegates at the Convention - save perhaps those who live in Ohio - have disrupted their lives to fly to, stay at, and attend the Convention daily.

The daily events are so unimportant to Trump? Or perhaps his business interests are so demanding that he can't be gone for more than a day or two (what does that say about his lack of availability to be President - part time?)

Though reading the actual author of 'Art of the Deal' it is more likely that his tiny attention span (10-15 minutes on one topic, and then becomes agitated) makes something like attending the full Convention would make him visibly on edge - bored and agitated. That is - he can't tolerate days of GOP speeches on GOP policies. Let that sink in.

Interesting. Also - it is very bad optics: "Why is he not in Cleveland?"
