Some Republicans have dismissed former Defense Secretary James Mattis' searing rebuke of President Trump — but not Sen. Lisa Murkowski (R-Alaska).

Mattis on Wednesday came out with a stunning rebuke of his former boss in The Atlantic, declaring that Trump "tries to divide us." Trump hit back on Twitter, and Sen. Lindsey Graham (R-S.C.) on Fox News accused Mattis of "buying into a narrative that I think is, quite frankly, unfair" to Trump. Other Republicans didn't seem to put a lot of weight in the comments, with Sen. Ron Johnson (R-Wisc.) telling CNN Mattis is "free to express" his opinion and Sen. John Kennedy (R-La.) telling NBC the comments weren't "especially helpful" but that he can "express himself" if he wants.

But then there was Murkowski, who told reporters she's "really thankful" for Mattis' "true, and honest and necessary" comments.

"When I saw General Mattis' comments yesterday, I felt like perhaps we are getting to a point where we can be more honest with the concerns that we might hold internally and have the courage of our own convictions to speak up," she said, CNN reports. Asked if she can still support Trump, Murkowski told reporters, "I am struggling with it," adding, "I have struggled with it for a long time, I think you know that."

Sen. Mitt Romney (R-Utah.) similarly told Politico that Mattis is an "American patriot of extraordinary service and sacrifice and great judgment," and he called the statement "powerful and stunning."
