So think about that for a minute. George W. Bush made a moving, eloquent plea for empathy and national unity, which enraged Donald Trump enough that he felt the need to go on the attack.

But there’s more. On the same weekend that he attacked Bush for making an appeal to national unity, Trump said this about Kim Jong Un, one of the most brutal leaders in the world: “I, for one, am glad to see he is back, and well!”

Then, Sunday night, sitting at the foot of the Lincoln Memorial for a town-hall interview with Fox News, Trump complained that he is “treated worse” than President Abraham Lincoln. “I am greeted with a hostile press, the likes of which no president has ever seen,” Trump said.

By Monday morning, the president was peddling a cruel and bizarre conspiracy theory aimed at MSNBC’s Joe Scarborough, a Trump critic, with Trump suggesting in his tweet that a “cold case” be opened to look into the death of an intern in 2001.
