Sen. Bernie Sanders speaking on June 21, 2017.

Vermont Sen. Bernie Sanders may have lost his bid for the White House in 2016, but he's sure as hell not ready to fade into obscurity anytime soon. Instead, he's emerged as a gadfly, loudly and publicly sounding the alarm on what he sees as the country's troubling descent into authoritarianism under President Donald Trump.

"I can't remember a president who has had more authoritarian tendencies than Trump," Sanders told me in an interview on Wednesday. "What is going on is not only this rise of authoritarianism but also, simultaneously, you are seeing this country move very rapidly toward oligarchy."
