In 1996, an 83-year-old Holocaust survivor and refugee to America sat down with an interviewer from the USC Shoah Foundation to recount what she had experienced.

“If we’re not going to tell now, in 20 years I don’t know who’s going to be to tell,” Rae Kushner said in her Yiddish-accented English. “And now we have still the strength and we have the power to do this and to warn the rest of the world to be careful who is coming up on top of your government.”

Rae’s grandson Jared is now one of the most powerful people in the U.S. government. President Trump’s son-in-law and a senior White House adviser, he is an influential voice on some of the nation’s most pressing issues, including immigration across the southern border. And to understand him, you need to understand his family story.

This episode is based on reporting from host Andrea Bernstein’s new book “American Oligarchs: the Kushners, the Trumps, and the Marriage of Money and Power.” Read more about the Kushner family at ProPublica and find an excerpt of Bernstein’s book at The New Yorker.
