Former Mayor Mike Bloomberg plans to march in the Israel Day Parade on Fifth Avenue in New York today, the Post has learned.

Billionaire Bloomberg is a staunch supporter of Israel and has long donated to Jewish causes.

While Bloomberg marched in the parades during his 12 years in office, a source familiar with the parade’s planning this year said the former mayor wanted to show his support because successor Mamdani is snubbing the march.

Mamdani is a staunch critic of Israel and even supports the boycott, divestment and sanctions movement against the Jewish state.

“This is Bloomberg sticking it to Mamdani,” a source familiar the parade’s plannning said.

Mamdani’s predecessor, former Mayor Eric Adams, also proudly announced he’s marching in Sunday’s pro-Israel Parade.
