Donald Trump criticises Vivek Ramaswamy publicly ahead of Iowa caucus

Ex-US president Donald Trump has criticized Vivek Ramaswamy, his closest ally in the Republican nomination race, alleging that the Indian-American entrepreneur is employing "deceptive campaign tactics." Trump's comments precede the Iowa caucuses on Monday, signaling the commencement of the extensive nomination process for both Republicans and Democrats in the upcoming presidential election. These remarks follow a sequence of comments and posts by the 38-year-old Ramaswamy that have irked Trump and his team. The former president's disapproval is triggered by the distribution of shirts by Ramaswamy's campaign bearing the slogan 'Save Trump, Vote Vivek.'
