"You might want to take care of your family first," he told Haley, a former U.S. ambassador to the United Nations and a former governor of South Carolina.
"Leave my daughter out of your voice," Haley shot back, adding under her breath, "You're just scum."
It was not the first time Haley, a foreign policy hawk, and Ramaswamy, an anti-interventionist on foreign conflicts, have clashed over TikTok.
Haley is vying with Florida Governor Ron DeSantis to become the top challenger to runaway favorite Donald Trump in the Republican nominating contest.
Ramaswamy, a relative unknown at the start of the year, gained buzz earlier this year but appears to have since lost momentum.
