Trump made the threat after Murkowski applauded a statement from former Marine Gen. James Mattis — in which the former secretary of defense castigated Trump as “the first president in my lifetime who does not try to unite the American people” amid nationwide protests over the police killing of George Floyd — as “true, and honest and necessary and overdue.”

“I made the comments that I made,” Murkowski told CNN on Monday. “I stand by them. Again, I think it’s important that we have a president who is working to bring people together. … And tone and words matter.”

She added, “I cannot live in fear of a tweet. That’s where I am now.”
