MSNBC’s Joe Scarborough excoriated President Donald Trump in a fiery Friday monologue, stunned by his support for North Korean dictator Kim Jong Un’s claim that he was not responsible for the brutal death of U.S. college student Otto Warmbier.

“Kim Jong Un was a murderer,” Scarborough said during his “Morning Joe” broadcast. “Nothing happens in that country that he doesn’t order. He is a tyrant of the first order and there is no way anybody would lay a hand on an American in North Korea unless Kim Jong Un was delivering the direct orders.”

Wrapping up his Hanoi, Vietnam, summit with Kim on Thursday, Trump said the ruler told him “he didn’t know about it, and I will take him at his word.” Instead, the president appeared to blame Warmbier’s fatal injuries on rough prisons.
