Yes, New York's Senator Charles Chuck Schumer is a Jew.
Schumer was born in Brooklyn, New York to Jewish parents, Selma Rosen and Abraham Schumer. He attended Harvard College, where he became interested in politics and campaigned for Eugene McCarthy in 1968. He continued to Harvard Law School, earning his Juris Doctor in 1974.
On May 15, 2009 news media reported that Arkansas State Senator and U.S. Senate candidate Kim Hendren called Senator Charles Schumer "that Jew."
He did correctly identify Schumer's religion, but some of the candidate's political opponents criticized the remark in its context as unacceptable, derogatory and an indication of prejudice.
Hendren apologized for his remark.
