President Donald Trump appears to have endorsed eugenics during a call in to “The Brian Kilmeade Show” on Friday, telling the Fox News host he believed the country has people in it who are “bad” because “there’s something wrong [with their] genetics.”

“A lot of them were let in here; they shouldn’t have been let in,” Trump said, referring to the perpetrators of a spate of recent attacks, including two men who brought explosives to a far-right protest outside New York City’s mayoral mansion earlier this month.

“Others, they’re just bad, they go bad. Something wrong,” he continued. “There’s something wrong. Their genetics are not exactly… they’re not exactly your genetic. It’s one of those problems, Brian. It’s a terrible thing. And it happens.”
