Then-Vice President Joe Biden apologized for using the word in 2014 after the ADL’s national director at the time issued a mild rebuke of his use of the word, saying Biden “should have been more careful.”

Biden made the reference in a speech while recalling anecdotes from his son’s experience serving in Iraq and meeting members of the military who were in need of legal help because of problems back at home.

“I mean these Shylocks who took advantage of, um, these women and men while overseas,” he said.

Some Democrats were quick to criticize Trump’s use of the word on Thursday.

“This is blatant and vile antisemitism, and Trump knows exactly what he’s doing,” Rep. Daniel Goldman of New York wrote on social media. “Anyone who truly opposes antisemitism calls it out wherever it occurs — on both extremes — as I do.”

Amy Spitalnick, the CEO of the Jewish Council for Public Affairs, said on social media: “Shylock is among the most quintessential antisemitic stereotypes. This is not an accident. It follows years in which Trump has normalized antisemitic tropes and conspiracy theories — and it’s deeply dangerous.”
