Kelly Sadler has left her job at the White House. No one out here in Flyover Country had ever heard of her, until she popped off about Sen. John McCain in a closed-door meeting.

Bad call, Ms. Sadler.

Sen. McCain had called waterboarding “torture” and urged his Senate colleagues to reject the nomination of Gina Haspel to lead the CIA; he cited Haspel’s role in an “intensive interrogation” program. McCain knows torture, as he endured more than five years of it as a Vietnam War prisoner.

Sadler’s response? She “joked” that McCain’s criticism “doesn’t matter; he’s dying anyway.” What a knee-slapper.

She’s now gone. Donald J. Trump ordered a White House communications office revamping. Sadler is a casualty, having been shown the door.

McCain, of course, is battling a grievous illness. Sadler’s comment was totally, unequivocally out of bounds. It was tasteless and crass in the extreme.

I’m glad she’s gone. However, the president has not yet issued a public rebuke of the comment. He hasn’t yet said a word about how sorry he that a distinguished American politician was ridiculed by someone on his staff. The president has yet to say a word on McCain’s behalf or a word wishing him well as he battles brain cancer.

Oh, no. The housecleaning is aimed at plugging the leaks that made Sadler’s hideous “joke” public.

I am left, therefore, to conclude that Trump really is as heartless as other critics have concluded. A man with a heart would have told Sen. McCain he is sorry for the remark and then he would have fired — on the spot — the person who blurted it out.
