'Dissent is as American as apple pie': Trump's UN ambassador Nikki Haley insists that she challenges the president 'directly' in opinion column rebuking anonymous op-ed

Nikki Haley, President Donald Trump's ambassador to the United Nations, would like you to know she is displeased with the unnamed Trump administration official who wrote a New York Times op-ed declaring themselves part of an internal "resistance" against the president.

Haley published counter-op-ed in The Washington Post on Friday, rebuking the anonymous author who painted Trump as petulant, unintelligent, and ill-suited for the Oval Office.

"What this 'senior official in the Trump administration' has done, and is apparently intent on continuing to do, is a serious disservice — just to the president, but to the country," Haley wrote, echoing a common refrain coming from inside the administration this week.

Like the White House press secretary Sarah Huckabee Sanders, Vice President Mike Pence, adviser Kellyanne Conway, and others, Haley invited the unnamed author to resign if they're truly unhappy with the way Trump governs.

But unlike others among Trump's inner circle, Haley did not offer a full-throated endorsement of the president.

"I don't agree with the president on everything," Haley said. "When there is disagreement, there is a right way and a wrong way to address it. I pick up the phone and call him or I meet with him in person."

Indeed, Haley has not been shy about breaking with Trump on some issues.

"Everyone in government owes a greater loyalty to our country and our Constitution than to any individual officeholder," wrote in The Post on Friday.

"Dissent is as American as apple pie. If you don’t like this president, you are free to say so, and people do that quite frequently and loudly," Haley said.

She continued: "But in the spirit of civility that the anonymous author claims to support, every American should want to see this administration succeed. If it does, it’s a win for the American people."
