One of the ringleaders of the Delaney Hall mayhem is a former New Jersey early-childhood teacher, The Post has learned.
Anti-ICE demonstrations have raged outside the federal immigration detention center in Newark since May 22, when 300 migrants inside went on a hunger strike over what they claimed were inhumane conditions.
Ex-teacher Cassandra Magazino, a “nonbinary” radical activist who lives in Pompton Plains, immediately started clamoring to “free the detainees” and “abolish ICE.”
“No concentration camps in New Jersey!” Magazino, 36, raged on Threads under the moniker “Rainbow Renegade,” which she’s used to organize the two-week long protest that’s resulted in officers being bitten by raging protesters, dozens of arrests, and a 9 p.m. curfew imposed by Newark’s mayor.
“More bodies are needed at Delaney Hall!” she said on May 28.
Soon also orchestrated the collection of military-grade riot gear, and personally delivered supplies to the protesters — coordinating pickups as many as three times a day outside public libraries and churches throughout the Garden State and recruiting volunteers to help, her social media posts show.
“Do we have any friends willing to spend a few hours at their local library tomorrow to collect supplies?” she asked. “Any friends with a storefront that would be willing to collect supplies?
“I will come around and pick up everything afterwards, you do not have to worry about transporting it anywhere.”
Magazino asked for items such as face shields, military goggles, gas masks, helmets, shin guards, knee pads, and wipes to clean off tear gas — as she prepped rioters for the violent clashes against police and ICE outside the 1000-bed federal migrant-detainment facility.
The self-described “Jersey girl” had taught at KinderCare, “the nation’s leading provider of early childhood education,” in Whippany beginning in 2017, according to her LinkedIn page.
“Happy first day of pre-Halloween, here’s my classroom so far,” she proudly posted on Facebook in 2021. “Spoiler alert – these decorations will be staying up all year round.”
But sometime in 2024, she claimed, she was “forced to quit.”
“Too bad most of the people who should be seeing this blocked me after they forced me to quit,” she posted on Instagram in 2025, sharing the screenshot of a text from a friend who told her the early learning center was “stupid to lose” her.
“I quit that job a year ago and have been running my own small businesses since, you absolutely ignorant tw-t,” she replied to a mother who suggested her demise might have had something to do with her radical activism.
KinderCare told The Post that Magazino left voluntarily in mid-2024, but did not elaborate.
After leaving her teaching gig, the self-described “perpetually stoned witchy activist” threw herself wholeheartedly into fighting “the patriarchy” and “ICE nazis.”
“If I get shot and killed while protesting, do not hold a peaceful vigil for me,” she wrote in January after the death of Renee Good in Minnesota at the hands of ICE officers. “I am literally giving you permission to throw my dead body on the steps of the White House.”
She ranted last week: “ICE nazis are literally beating innocent people and pushing them into oncoming traffic in Newark. Just in case you guys needed a reminder of the fascist dictatorship we’re living in.”
The Delaney Hall protests are part of a well-funded effort bankrolled by some of the biggest far-left organizations in the country, with combined revenues of nearly $825 million, a Fox News Digital investigation found.
A document called the “Delaney Hall Creator Brief” outlined talking points for activists, such as calling the detention center a “concentration camp” — as Magazino has — by agitators who conceal the real identities under online monikers.
“They know what they are doing is wrong. They don’t want you to know who is in charge,” said former US Senate Chief of Staff Chuck Flint, a nonprofit expert.
Magazino has deleted both her personal and “Rainbow Renegade” activist Instagram pages after The Post left messages seeking comment, which she did not return.
