Nikki Haley's son Nalin, 22, gives brutal Trump-style nicknames to his mother's former rivals Sen. Tim Scott and Vivek Ramaswamy

Nikki Haley's 22-year-old son has adopted the Trumpian way of awarding derogatory nicknames to his mother's previous primary election rivals.

Nalin Haley, a senior at Villanova University, dubbed Sen. Tim Scott (R-S.C.) as a traitor with the name 'Senator Judas' and compared biotech entrepreneur Vivek Ramaswamy to the likeness of the clown Pennywise from the horror film It.

Both Scott and Ramaswamy were once among the top competitors in the Republican primary field. Both dropped out and have since endorsed former President Donald Trump.

Ramaswamy spokeswoman Tricia McLaughin questioned in a statement to DailyMail.com: 'Didn't Haley say to keep the kids out of it and now she's using them as attack dogs?' 

Nalin and his sister Rena, 26, have joined their mother on the campaign trail while their father and the 2024 hopeful's husband Major Michael Haley is deployed in Africa with the South Carolina Army National Guard.

At a rally in Gilbert, South Carolina on Saturday, Nalin took time during his remarks introducing his mother to attack Scott, who has become a top surrogate for Trump in the Palmetto State.

'We had a lot of them go up to New Hampshire, Nalin noted, 'and I saw Trump standing side by side, he was next to Senator Judas — excuse me, Senator Scott,.'

This jab earned him 'oohs' from the audience, with one crowd member saying, 'Ouch.'

Nalin claims with the nickname that Scott betrayed his mother when he endorsed Trump for president upon dropping out of the race last year.

Haley appointed Scott to the Senate in 2012 when she was governor of South Carolina.

At one rally, Haley joked she would 'deal with' Nalin after he attacked her rivals.

Meanwhile, Nalin also had some fierce criticism for Ramaswamy, who at a Republican presidential debate last year brought up Haley's daughter's use of TikTok amid criticizing her for her stances on China. 

'My mom had a talk with me, and I was like, you know what? I feel awful, and I would like to take this chance to apologize to Pennywise,' Nalin said during remarks in Summerville, South Carolina on Tuesday in reference to a previous criticism of Ramaswamy.

'Because Pennywise is a lot less creepy, a lot less of a clown, and he has a much better hairline than he [Ramaswamy] does,' he added.

Nalin also compared Ramaswamy to the clown Pennywise from the horror film It – specifically pointing to head shape and hairline

This was a callback to his original attack against Ramaswamy last year after the biotech entrepreneur got personal going after Rena.

'Vivague Ramaslimey backpedaling more than his receding hairline,' Nalin wrote on X, formerly Twitter, the day after November's heated Republican presidential primary debate.

Just moments later on November 8, he posted an image of the clown Pennywise from the horror film It and said he was 'having trouble' finding the difference between the two – specifically pointing to the shape of their heads and hairline.

McLaughlin responded to the insult with a statement provided to DailyMail.com: 'In most cases of campaign banter, I give credit where credit's due, but in this case, I hope he can develop his trash-talking arsenal to include something that's mildly funny.'
