That goes back to not having figured out the president thing. Mostly I think it's a 'I have to have an audience' ego stroke. Another reason why he watches the news on Fox (about him) every morning. When they don't build up his ego he tweets them down like he does everyone that crosses him.
I don't tweet and I don't know anyone who does. Mostly they text ( boomer/millennial) or use Instagram (younger generations). I'm trying to figure out who his adoring audience is. Maybe his twitter account is his official position on all things of any importance to him but it leaves a lot of people out of the loop, including our military.
