what offices related to israel did mamdani relinquish

Zohran Mamdani did not relinquish any office “related to Israel” in the reporting I found; instead, he revoked or kept certain city policies tied to Israel and antisemitism. The office he kept was the New York City office to combat antisemitism, while he revoked an order that barred city agencies from boycotting or divesting from Israel and another that adopted the IHRA antisemitism definition.

What was changed

• He revoked the order banning city agencies from boycotting or divesting from Israel.

• He revoked the order adopting the International Holocaust Remembrance Alliance definition of antisemitism.

• He did not dismantle the office created to combat antisemitism.

Plain-English reading

If your question was about an actual office , the answer is that he did not give one up in the sources I found. If you meant which Israel-related actions or positions he rolled back, those were the two executive orders above.

TL;DR

Mamdani kept the antisemitism office, but he removed two Israel-related Adams- era policies.
