Grok:
Yes, Minneapolis Mayor Jacob Frey is Jewish. He was born into a Jewish family—his mother has Russian-Jewish roots, and his father converted to Judaism—and identifies as a Reform Jew, drawing on his faith for guidance in public life, especially amid rising antisemitism since October 2023.
He attends Temple Israel, a prominent Reform synagogue in south Minneapolis (about six miles from City Hall), along with his wife Sarah Clarke (who converted to Judaism after their marriage) and their two young daughters. The family has been members there for years, and Frey has publicly condemned antisemitic vandalism targeting the synagogue in recent incidents. Note that an older 2021 interview mentioned affiliation with Shir Tikvah as well, but more recent sources confirm Temple Israel as his primary congregation.
Did he deliver the speech in Somalian from the barred window of an outbound cattle car?
