I watched Trump's news conference. It was difficult. I'm not a Trump hater, nor am I in love with him. I think he's president because he was the lesser of evils (ABC -- Anybody But Clinton). I think the guy has ADHD or something as he doesn't seem to be able to complete a thought without going out in left field, off topic, and sometimes never gets back to the original topic.
During his time in office, I've agreed with those who felt he wasn't acting "presidential", esp with all of the scattered thought in his tweets. Still, one has to acknowledge results. The economy is perceived as being great. Business is booming. Wages (and prices) are on the upswing, as is the stock market.
As Simon noted, no new wars -- not even with Little Rocket Man. In fact, Kim seems to be cleaning his act up (if we can believe what is reported). I think Kim was actually afraid that "crazy man Trump" might shoot back at him or even "shoot first".
As far as the press corp, they make it pretty clear that they don't like the man, so why should he bend over and kiss their asses? The press doesn't like the fact that they did not get to choose who got elected this time. They clearly favored Clinton, just as they ordained Obama 8 years prior and glossed over any of Obama's gaffs (ie, "we have campaigned in 57 States" -- SNL would have ripped up George W. if he ever made such a dumb ass statement). Fifty years ago, Walter Cronkite was the most trusted man in America. Now mainstream media has sunken to the level of the National Enquirer. Sensationalism sells. Trump treated the reporters with the same disdain as they treat him.
