Nikki Haley received a hero's welcome at AIPAC on Monday as she reminded the pro-Israel lobbying group of her early successes as U.S. ambassador to the United Nations and promised to continue with a sharp break from the Obama administration.

"For anyone who says you can't get anything done at the U.N., they need to know there is a new sheriff in town," Haley said during an appearance at AIPAC's annual conference in Washington, D.C.

The former South Carolina governor, drawing on her experience in retail politics, uncorked a series of red meat remarks attesting to the Trump administration's commitment to backing Israel. Her early advocacy at the UN — such as her successful demand that the UN withdraw a report accusing Israel of apartheid — has endeared her already to pro-Israel activists. It's also given the Trump team a success story at a time when other allies are uneasy about his foreign policy plans.

"I think this crowd would be thrilled to hear you for hours — days, weeks, months," Dan Senor, the former George W. Bush advisor who introduced Haley, said during the question-and-answer session.
