Former United Nations Ambassador John Bolton said Thursday that he would not shave his white mustache amid reports that it might have led President-elect Donald Trump to not choose him as secretary of state.

Bolton posted his decision on Twitter:

I appreciate the grooming advice from the totally unbiased mainstream media, but I will not be shaving my #mustache. — John Bolton (@AmbJohnBolton) December 22, 2016

The Washington Post reported earlier Thursday that Trump was considering appearances in his Cabinet picks — and the president-elect was not particularly enamored by Bolton's facial hair.

"Donald was not going to like that mustache," a Trump associate told the Post. "I can’t think of anyone that’s really close to Donald that has a beard that he likes."

Trump eventually said that he would nominate Exxon Mobil Corp. CEO Rex Tillerson to be the nation's top diplomat after his inauguration next month.

Overall, aides told the Post that they understood that the president-elect may rule out certain candidates based on his image of what a nominee should look like.

"That’s the language he speaks," the source said. "He’s very aesthetic.

"You can come with somebody who is very much qualified for the job, but if they don’t look the part, they’re not going anywhere."

Jason Miller, a transition team spokesman, said that Trump does factor in appearance in his appointment decisions.

"Presentation is very important because you’re representing America not only on the national stage, but also the international stage depending on the position," he told the Post.
