WASHINGTON (JTA) — Bill de Blasio, New York’s newly installed mayor, said defending Israel was part of his job.

“Part of my job description is to be a defender of Israel,” de Blasio said at a private New York event of the American Israel Public Affairs Committee, first reported Friday by the Capital New York news website.

“There’s no greater ally on earth, and that’s something we should say proudly,” he said at the Jan. 23 event.

De Blasio, elected in November described his visit to Israel with his family several years ago, and said that “City Hall will always be open” to AIPAC.

He noted in his talk that New York has the largest Jewish population outside of Israel.

Successive New York mayors have for decades cultivated close ties with Israel.

The AIPAC event was omitted from the mayor’s schedule distributed to the press corps, Capital New York reported in a follow-up article. The mayor said it was because AIPAC wanted the dinner to be closed to the press.

De Blasio promised to provide a “clearer understanding” of his schedule and speeches, in the wake of the AIPAC speech, according to Capital New York.
