NEW YORK (AP) — New York City’s rank-and-file police union is urging its members to ban Mayor Bill de Blasio from their funerals.

The Patrolmen’s Benevolent Association posted a link on its website telling members not to let de Blasio and City Council Speaker Melissa Mark-Viverito “insult their sacrifice” should they be killed in the line of duty. The union posted a waiver officers can sign requesting the two politicians not attend their funerals due to their “consistent refusal to show police officers the support and respect they deserve.”

The New York Post reports the mayor and council speaker are calling the effort “deeply disappointing.”

The mayor customarily attends such funerals.

The union’s president has said officers haven’t felt supported in the wake of a chokehold death of an unarmed black man.
