US President Donald Trump's top trade advisor Peter Navarro called billionaire Tesla CEO Elon Musk a "car assembler" and not a "car manufacturer". Speaking to CNBC about Musk reportedly wanting Trump to reduce reciprocal tariffs, Navarro said, "[Musk] wants cheap foreign parts...But we want them home." Musk reacted saying Navarro is "truly a moron" who's "dumber than sack of bricks".
