Former President Trump criticized Vivek Ramaswamy, a friendly campaign rival, for deceitful campaign tactics.
Trump reacted to Ramaswamy's 'Save Trump, Vote Vivek' shirts, stating a vote for Ramaswamy aids the 'other side' and isn't MAGA-aligned.
Trump's team also denounced the claim as fraudulent.
Ramaswamy, while respecting Trump, warned of a system trying to eliminate Trump from the race.
This marks a shift in Trump's approach, as he previously avoided criticizing Ramaswamy due to his support.
The conflict arises just before the Iowa caucuses.
