Billionaire Elon Musk has pushed back against US President Donald Trump's veiled threat of deportation to South Africa. Trump told reporters he'd have to "take a look" at possibility of deporting Musk, to which Musk reacted, "So tempting to escalate this...I'll refrain for now". Musk, who became naturalised citizen of US in 2002, had criticised Trump's 'Big Beautiful' tax bill.
