Donald Trump has shown an ability to hire a wide-ranging array of key administration officials. They run from the brightest of lights to the dimmest of bulbs.

I consider Defense Secretary James Mattis to be among the stars of the Trump administration. He’s a retired four-star Marine Corps general; tested in combat. He’s dedicated to the defense of this country. Thoughtful, learned and a totally competent strategic thinker.

I hope he stays for the duration of the Trump administration, although Mattis’s tenure is beginning to show signs of wobbliness.

Then there’s the president’s latest selection to be our ambassador to the United Nations.

I am having difficulty wrapping my noggin around this one. Heather Nauert is nominated to be our nation’s top envoy on the world stage. Her credentials? None. She has nothing to offer.

Except for this: She once was a “news” personality on the Fox News News Channel, the president’s network of choice. She did a co-hosting gig on “Fox & Friends.” She dressed up in goofy costumes and acted totally, well, the way morning “news” talk show co-hosts often act.

Then she got a job as spokeswoman for the State Department. You might be recall how she sought to praise U.S.-Germany relations by citing, for instance, the upcoming D-Day commemoration. D’oh! Wait a second!

Our guys fought the Germans to the death on the beaches at Normandy, France. We were at war.

This is the kind of “experience” the president sought when he named this person to be our advocate on at the United Nations.

Weird, man.
