9/11 families confronted NYC Mayor Mamdani on city hall steps, demanding he skip Friday's 25th anniversary ceremony.

One victim's daughter—who was 9 when her father was killed—told him bluntly: "Dude, we DO NOT want you to come."

Families cited Mamdani's associations with Hassan Piker, advisor Ramzi Kassem, and an imam allegedly linked to the 1993 World Trade Center bombing as reasons for their objection.

The standoff comes just days before the September 11 memorial event.
