A sickle to the back!

Mayor Zohran Mamdani’s allies are publicly breaking with him over his handpicked police commissioner — and Hizzoner is livid that the socialist House candidate he went out on a limb to endorse is leading the charge.

City Hall staffers have been openly whining about alleged ally Darializa Avila Chevalier — whom Mamdani endorsed just a few months ago during the primaries — after she led a crusade to slam NYPD Commissioner Jessica Tisch after ICE agents shot an illegal migrant in the Bronx.

“They were pissed about what she did on social media and her public rhetoric on NYPD,” one source with knowledge said. “City Hall was like, ‘what the f–k are you doing!’”

The ICE shooting may mark the end of the socialist honeymoon for some Mamdani supporters, as some lefty pols and the national branch of his comrades in the Democratic Socialists of America push for Tisch’s ouster despite Hizzoner standing by his commissioner.

Another source said that folks in the admin griped that, “this was a direct undermining of Mamdani.”
