Vice President Joe Biden made an impassioned case against Donald Trump’s character on Thursday, saying the GOP nominee didn’t understand the burdens faced by everyday families, especially when someone loses a job.

“My biggest problem with Donald Trump ... It’s not his cockamamie policies, it’s the way he treats people,” Biden said during a campaign stop for Hillary Clinton in Warren, Ohio. “Think about growing up in your house, at your kitchen table, if you ever talked about people like he does. I’m not joking, I really, genuinely mean this: If you ever sat there and talked about how cool it was that John down the street got fired. ‘You’re fired,’ a phrase he’s made famous. ‘You’re fired.’”

“You oughta come from a household where people were fired. Where the plant closed down. Where all of a sudden they’re staring at the ceiling wondering, ‘How in God’s name am I going to make it?” Biden continued, his voice rising. “I’m being deadly earnest here, this part’s not the campaign speech, man, this is about the character of the person we’re talking about electing as president of the United States.”

Trump, who built his empire on the wealth of his father, has insisted that he has made sacrifices in his business career. But pressed to name any by ABC’s George Stephanopoulos in July, he struggled to name any real ones, simply saying that he had created jobs and built “great structures.”

In his remarks, Biden pointed to the advantages Trump had been given in his life.

“[Trump] was born with a silver spoon in his mouth that he’s now choking on because his foot’s in his mouth along with the spoon,” he said.
