Asked what threats she worries could blindside the U.S. amid what federal officials have called a heightened threat level during the Israel-Hamas war, Haley focused on "foreign infiltration."

"America right now is acting like it's Sept. 10. We better remember what Sept. 12 felt like, because it only takes one," she said.

"We've got to get the foreign infiltration out of our country -- whether it's in our schools, whether it's on our social media, we need to stop all foreign lobbying that's happening to members of Congress, and we need to start securing America again," she continued.

Ramaswamy again trained his ire toward Haley, with whom he has feuded across the debates this year, saying she was “woke” and “had a corruption problem.” Ramaswamy raised a notepad which had the message “NIKKI=CORRUPT.” A chorus of boos filled the venue.

The entrepreneur said Haley would “send your kids to die so she can buy a bigger house.”

Given the chance to respond, Haley said only, “No. It’s not worth my time to respond to him.”

In that question, Tom Fitton just pointed out, incredulously, that the U.S. Postal Service is more popular than the FBI. But this actually isn’t surprising -- the Postal Service is quite popular! According to a 2023 poll from the Pew Research Center, 77% of Americans have a favorable view of the Postal Service. It’s the second-most popular federal agency, after the National Park Service.

PolitiFact rated Ramaswamy’s claim false after he introduced it at the second primary debate.

In the past, the medical community used to view the experience of being transgender as a "disorder," but they no longer agree on that categorization. In the last decade, diagnostic manuals published by the World Health Organization and American Psychiatric Association contained updated language to clarify that being transgender is not a mental illness.
Experts told us that persistent gender dysphoria can cause other mental health issues, but it is not itself a mental health disorder.

Haley continues to face blowback over her proposed requirement that every person on social media be verified by their name and banned from posting anonymously -- a position she later walked back slightly.

"She should come nowhere near the levers of power, let alone the White House," Ramaswamy said, calling the position "fascism."

Haley responded, "What I said was that social media companies need to show us their algorithms."

"I also said there are millions of bots on social media right now," she continued. "They're foreign, they're Chinese, they're Iranian. I will always fight for freedom of speech for Americans. We do not need freedom of speech for Russians and Iranians and Hamas. We need social media companies to go and fight back on all of these bots that are happening."

DeSantis pushed back on her characterization of her past comments.

"You can roll the tape, she said, 'I want your name' and that was going to be one of the first thing she did in office," the Florida governor said. "She got real serious blowback and understandably so, because it'd be a massive expansion of government."
