Kelly Sadler works in a White House where the Big Man — the president — never apologizes for anything.

She need not follow Donald John Trump’s lead. All she has to do to make an idiotic story dissipate is to apologize publicly to the man she disparaged so cruelly.

The man is Republican U.S. Sen. John McCain. He is fighting a grievous illness, brain cancer. Sadler, a mid-level White House communications office staffer, was attending a private meeting when she blurted out an insult directed toward Sen. McCain.

McCain had spoken against CIA director nominee Gina Haspel. He doesn’t like her stance on torturing enemy combatants. He has urged his Senate colleagues to reject her nomination to lead the CIA.

Sadler said McCain’s objection “doesn’t matter because he’s dying anyway.”

The story won’t go away. It should go away. All the staffer has to do is to stand before the nation and say she is sorry for her disparaging remarks aimed at a genuine war hero. You see, Sen. McCain’s opposition to torture comes the hard way: He experienced more than five years of it while being held captive during the Vietnam War.

Sadler’s demeaning remark has no place coming out of the mouth of a White House official who, I hasten to add, works for the public. That’s you and me, dear reader.

The president is entitled to withhold any apology if he chooses. My hope is that he hasn’t instructed Kelly Sadler to follow him down the path of arrogance.

My fear, though, is that he has done precisely that very thing.

Shameful.

Matt Schlapp needs to be slapped bald-headed.

The conservative activist has taken up some form of defense for the White House communications aide who said that Sen. John McCain’s criticism of CIA nominee Gina Haspel “doesn’t matter, because he’s dying anyway.”

The aide’s name is Kelly Sadler. Schlapp has defended her saying she’s a “little bit of a victim.”

No she’s not! She’s a thoughtless mid-level clown who popped off in private with what has been described as a “bad joke.”

McCain doesn’t like Haspel’s view of torturing enemy combatants. He urged the Senate reject her confirmation. Yes, he’s battling a life-threatening disease. However, he is of sound mind and is entitled to speak his mind about an important policy matter. And there is no one in the U.S. Senate who is more qualified to speak about torture than McCain, a former Vietnam War prisoner who endured years of torture at the hands of his captors.

Sadler popped off thoughtlessly.

Schlapp said this, according to The Hill: “Kelly is my friend. I feel bad she is going through this. She immediately called to apologize. She’s also a little bit of a victim here,” Schlapp told CNN “New Day” co-anchor Chris Cuomo.

The story has gotten national attention. It has serious legs and is threatening to keep on running until Sadler owns up publicly to her idiotic comment.

Spare us the indignation, too, over the leaking of the comment to the media. Big deal. All of those in the room are answerable to the public in the first place and millions of us out here way beyond the Beltway are damn angry that a White House functionary would be so cruel — even in “private.”
