Hillary Clinton campaign operatives didn’t like New York City Mayor Bill de Blasio speaking his mind to reporters last summer.

Senior-level aides circulated a number of statements de Blasio made about Clinton they perceived as critical of her in June of 2015.

Communications staffers and campaign manager Robby Mook shared tweets from a Politico reporter stating that de Blasio would not be attending a Clinton rally.

“I’m waiting to hear … her larger vision to addressing income inequality,” Politico reporter Azi Paybarah quoted de Blasio as saying.

After communications aide Kristina Schake forwarded the message to Mook on June 10, 2015, and he responded, “Wow. What a terrorist.”

“Told you!” Communications Director Jennifer Palmieri added.

“Can we talk about calling him?” Huma Abedin replied.

“He and (Police Commissioner Bill) Bratton did a press conference today – he said all of this there,” Schake wrote back to Abedin. “We are pulling the transcript.”
