🚨WHOA. The El Paso Medical Examiner says it will rule the death of a 55-year-old Cuban man at ICE's "Camp East Montana" tent camp as a homicide.

He was allegedly choked to death by a guard during a "struggle" after he refused to enter a housing unit without his medications.
By Douglas MacMillan When U.S. Immigration and Customs Enforcement announced the Jan. 3 death of detainee Geraldo Lunas Campos at a Texas detention camp, the agency said “staff observed him in distress,” and it gave no cause of death. An employee of El Paso County’s Office of the Medical Examiner told Lunas Campos’s daughter this week that, subject to results of a toxicology report, the office is likely to classify the death as a homicide, according to a recording of the conversation. In the recording, which the daughter shared with The Washington Post, the employee said a doctor there “is listing the preliminary cause of death as asphyxia due to neck and chest compression,” which means Lunas Campos did not get enough oxygen because of pressure on his neck and chest. Pending the results of a toxicology report, the staffer said on the recording, “our doctor is believing that we’re going to be listing the manner of death as homicide.” In an interview with The Post, Santos Jesus Flores, a man who says he was detained in the segregation unit the day Lunas Campos died, said he saw at least five guards struggling with Lunas Campos after he refused to enter the segregation unit, complaining that he didn’t have his medications. Flores said he saw guards choking Lunas Campos and heard Lunas Campos repeatedly saying, “No puedo respirar” — Spanish for “I can’t breathe.” Medical staff tried to resuscitate him for an hour, after which they took his body away, Flores said. “He said, ‘I cannot breathe, I cannot breathe.’ After that, we don’t hear his voice anymore and that’s it,” said Flores, who had contacted a family member of Lunas Campos, who in turn put him in touch with a Post reporter. The Post confirmed Flores was in Camp East Montana through ICE’s detainee locator.

THREAD of offers of guest lectures (via Zoom) for Minneapolis-area classes so faculty can offer their students a top-quality education while dealing with other crises

As a result of Regent Rennison's vote, Democrats may no longer control the CU Board of Regents. But, we the people remain united against MAGA's repellant vision for higher ed, and we will continue to use every tool at our disposal to resist it.
Here's our full statement on this morning's vote:
Colorado Working Families Party Statement on CU Board of Regents Chair Election: “Today, Democrat Callie Rennison - who represents CD2, one of the bluest districts in the state - ensured that she will forever go down in Colorado history as our own version of Kyrsten Sinema. She has betrayed her own party, belied every commitment she made to us when we endorsed her, and disrespected the will of the voters who elected a Democratic majority to lead the CU Board of Regents. Even worse, she did so while the Trump administration is doubling down on vicious and unprecedented attacks on civil rights, civil liberties and academic freedom on campuses across the country. “Rennison has ensured that her legacy will forever be that she is remembered as the Democrat who actively chose to betray immigrants, LGBTQ+ people, workers’ rights, and academic freedom in the CU system. Every MAGA abuse brought to bear on the CU community as a result of handing control of the Board of Regents to a Republican will be enabled by her complicity. The greatest memory of her time as a Regent will be that she was a turncoat who empowered Donald Trump to more deeply abuse the University of Colorado, and any other thing she has done will be lost in the shadow of her great betrayal. (1/2) “We want to thank At Large Regent Elliott Hood for stepping forward to run as Chair. With a Democratic majority, there is no reason he should not have earned that title. We are also incredibly thankful for WFP champion and CD6 Regent Ilana Spiegel, and progressive CD1 Regent Wanda James, who each continue to demonstrate incredible leadership in this critical moment, and who worked tirelessly to engage both key leaders and everyday Coloradans in this vital discussion about the future of Colorado’s flagship university system. These are the leaders who are truly fighting Donald Trump’s abuses of all of us -- but unfortunately they were betrayed by a Democrat In Name Only who chose to support a Republican power grab. “Coloradans will be watching what this new GOP Chair and his enabler do - and you can be sure that every MAGA attempt to abuse the people of the University of Colorado will be met with the fiercest of resistance. Democrats may no longer control the system’s governing body as a result of Rennison’s betrayal, but we the people are united against Donald Trump’s repellant vision for higher education, and we can and will continue to use every tool at our disposal to resist it.” Wynn Howell, Colorado Working Families Party State Director (2/2)

Stage 5 pundit-brain is watching an innocent woman being killed by agents of the state and going, "hmm this says a lot about the urban-rural divide in America."
What did the regulars make of it? Ms. Good’s death was tragic, they said. Horrific. But they also said that she had asked for trouble. “You obey the law officer,” a man in a veteran’s ball cap said, “and question it later.” This is the divide, in a single sentence. In Minneapolis, protesters saw an innocent woman killed by a federal agent and took to the streets. At “the Pickle,” the regulars saw a woman who should have complied. In bars, cafes and coffee shops across rural Minnesota, the same conversations were unfolding. Ms. Good’s death had become a mirror, reflecting back a fracture that had been deepening for years — not just in their state, but across the country, wherever rural areas chafe against the political power of big cities.
