Baio, who spoke at the 2016 Republican National Convention in support of former New Yorker and newly minted fellow Floridian Donald Trump, is best known as Chachi Arcola on the 1970s and ’80s sitcom “Happy Days” and the titular character on the 1980s sitcom “Charles in Charge.” Now in his sixties, Baio all but gave up acting almost a decade ago but did appear in a little-seen 2021 comedy film called “Courting Mom & Dad.”
