Feud flared up when president-elect chose Sriram Krishnan, an Indian-born entrepreneur, as his AI adviser

Bitter in-fighting has broken out between the tech billionaire Elon Musk and Donald Trump’s hardline Make America great again (Maga) base after the US president-elect chose an Indian-born entrepreneur to be his adviser on artificial intelligence.

The row has pitted Musk and his fellow entrepreneur Vivek Ramaswamy against diehard supporters including the far-right activist Laura Loomer and Matt Gaetz, the former Congress member and abortive nominee for attorney general. The spat threatens to open up a chasm among Trump’s supporters over immigration, a key issue in his election victory.
