'He is dumber than a sack of bricks,' Musk said once about Trump's anti-India aide Navarro
Peter Navarro, who is an adviser to US President Donald Trump, was called dumber than a sack of bricks by billionaire Elon Musk in April. "Navarro is truly a moron," Musk had said when Navarro claimed Musk is more of a "car assembler" than a "car manufacturer". Navarro has been criticising India over the purchase of Russian oil.
