There was absolutely nothing to be embarrassed about in Trump's comment.

What kind of a deal is it to swap Brittney Griner, a basketball player who openly hates our Country, for the man known as “The Merchant of Death,” who is one of the biggest arms dealers anywhere in the World, and responsible for tens of thousands of deaths and horrific injuries. Why wasn’t former Marine Paul Whelan included in this totally one-sided transaction? He would have been let out for the asking. What a “stupid” and unpatriotic embarrassment for the USA!!!
If you so concerned about this comment, I can't help you further.
