CEO resigns from Trumps' council and Trump immediately goes to Twitter to denounce and insult him.  The statement from Frazier:

"America's leaders must honor our fundamental values by clearly rejecting expressions of hatred, bigotry, and group supremacy, which run counter to the American ideal that all people are created equal," Frazier said in a statement on Monday.

He added: "As CEO of Merck, and as a matter of personal conscience, I feel a responsibility to take a stand against intolerance and extremism."
