Ms. Haley deflected on whether she supported a federal six-week abortion ban such as the one her home state of South Carolina recently passed. Any national restrictions, she said, would require 60 senators to approve, which she said was so remote that the question barely merited consideration.
In the most stirring moment of the night, Ms. Haley described persuading reluctant Republican lawmakers in South Carolina to remove the Confederate battle flag from the State Capitol after the massacre by a white supremacist of Black worshipers at the Mother Emanuel church in Charleston in 2015.
She agreed with barring transgender girls from school sports and even seemed to suggest that allowing “biological boys” in girls’ locker rooms was connected with the high rate of teenage girls who have considered suicide.
At the same time, she acknowledged that “we do need to be humane” about transgender children. In South Carolina schools when she was governor, Ms. Haley said, principals made private bathroom accommodations for them. “They were safe, and the majority of the student body didn’t even have to deal with it,” she said.
Haley made a strong contrast with Trump and DeSantis on foreign policy.
Ms. Haley also carved out differences with Mr. Trump and Mr. DeSantis on foreign policy issues, as she has in the past. The former U.N. ambassador disputed Mr. DeSantis, who has called Russia’s invasion of Ukraine a “territorial dispute” — a characterization he has since walked back — and she dismissed Mr. Trump’s refusal to say whether Ukraine should win the war.
She said both positions represented a naïve trust in Russia’s president, Vladimir V. Putin. “If Ukraine pulls out,” Ms. Haley said, “then we’re all looking at a world war.”
Asked by Mr. Tapper about Mr. Trump’s congratulating North Korea’s leader, Kim Jong-un, for recently ascending to a leadership role in the World Health Organization, Ms. Haley called Mr. Kim, whose flattering letters Mr. Trump once praised, a “thug.”
“There is no reason we should ever congratulate the fact that they are now vice chair of the World Health Organization,” Ms. Haley said.
