Robert F. Kennedy Jr., President-elect Donald Trump's pick for secretary of Health and Human Services, has a long history of scathing critiques against Trump, labeling him a "threat to democracy," a "bully," and, as recently as July, a "terrible president." But Kennedy's harshest attacks date back to Trump's rise in 2016, when on his radio show "Ring of Fire," Kennedy applauded descriptions of Trump's base as "belligerent idiots" and suggestions that some were "outright Nazis" and "spineless fellow travelers." Kennedy also likened Trump to historical demagogues like Adolf Hitler and Benito Mussolini, accusing Trump of exploiting societal insecurities and xenophobia to amass power.
