Navarro was no medical expert. His hyperbolic personality and over-the-top hostility toward China made it easy to write off his alarm. He played rough, and he often inserted himself in White House fights far outside his official lane, which in theory was trade and manufacturing. Like Trump, he fancied himself an expert on many things or at least so smart that he could become one overnight. Some of his colleagues therefore had a hard time reconciling their view of Navarro as a rogue actor with the reality that he could still be right about the emerging threat.
