President Donald Trump’s choice for national security adviser, retired Vice Admiral Robert Harward, has turned down the offer, a senior White House official said on Thursday.

A friend of Harward's says he was reluctant to take NSA job bc the WH seems so chaotic; says Harward called the offer a "shit sandwich."

shit sandwich (plural shit sandwiches)

(informal, vulgar) Something highly undesirable which can not be ameliorated, but only endured.[1]
