With 8 agreements added, today's updates also bring us to a new insane mark in the program's growth ⤵️ ICE is now partnering with county law enforcement agencies (mainly sheriffs' offices) in 25% of *all U.S. counties*. 786 of the 3,144 county-level governments now have an active agreement.

Another immigration judge hired by the Trump admin promoted the Pizzagate conspiracy theory, said Haitian migrants were "invading" Ohio, and openly said he wanted to help ICE, who will be one of the parties appearing in front of him as an immigration judge.
Some of the recruits were not shy about sharing their thoughts about divisive issues online before their hiring. Nathan M. Hansen, a Minnesota lawyer, was appointed this month, more than a year after he lost a race for district judge. He had shared social media posts about the “Haitian invasion of Ohio” and promoted right-wing conspiracy theories such as Pizzagate, about a rumored child sex ring operating from a D.C. pizzeria, the Minnesota Reformer recently reported.

After Trump’s immigration raids triggered protests in Minneapolis, Hansen posted on Facebook, “Is there anything we can do to help ICE if we want to?” He did not respond to a request for comment.

Hansen is serving in the Twin Cities area.

Let me explain what this genuinely EVIL memo does. The admin is doubling down on its plan to arrest, detain, and interrogate tens of thousands of legally present refugees; people already vetted who’ve lived here legally for 1+ year. Hundreds were arrested in Minnesota before a court blocked this.
П.
New Policy
When a refugee is admitted to the United States, the admission is conditional and subject to a mandatory review after one year of physical presence in the United States under INA § 209(a)(1), 8 U.S.C. § 1159(a)(1). [footnote 1] At one year after admission:

[Footnote 1] 18 C.F.R. § 209.1(a)(1) states that every refugee whose status has not been terminated "is required to apply to USCIS one year after entry in order for USCIS to determine his or her admissibility ." 8 C.F.R. § 209.1(b) provides that this [end fragment of footnote 1]

The refugee must return, or be returned, to Department of Homeland Security (DHS) custody for inspection and examination for admission as an LPR.
If the refugee does not voluntarily return, DHS will return the individual to custody (i.e., arrest and detain) for this purpose.
DHS may maintain custody for the duration of the inspection and examination process.
This detain-and-inspect requirement ensures that refugees are re-vetted after one year, aligns post-admission vetting with that applied to other applicants for admission, and promotes public safety.

Days after Secretary Noem took office, she purported to "vacate" decisions by Secretary Mayorkas to extend TPS for Venezuela and Haiti — even though the law says repeatedly that TPS, once granted, lasts until it expires. The 9th Circuit says she had no authority to do that.

NEW! Sworn declarations filed last night confirm the Trump admin sent INNOCENT people to rot in prison El Salvador, including a professional soccer player jailed and tortured by the Maduro regime, who entered this country LEGALLY to seek asylum, and who has NO CRIMINAL RECORD in either country.
I am the immigration attorney for Jerce Reyes Barrios, born in January 16, 1989 in Venezuela. 2. In February and March 2024, Mr. Reyes Barrios marched in two demonstrations in Venezuela protesting the authoritarian rule of Maduro. At the second demonstration, he was detained and taken to a clandestine building where he was tortured (electric shocks and suffocation) along with other demonstrators. 3. Shortly after his release, he fled Venezuela for the United States. He registered with CBP One in Mexico, then presented himself to CBP officials on the day of his appointment. He was taken into custody and detained at Otay Mesa Detention Facility in September 2024. 4. We applied for asylum, withholding of removal, and CAT protection in December 2024. His final individual hearing is set for April 17, 2025 before Judge Robinson at the Otay Mesa Immigration Court. 5. On March 15, 2025, Mr. Reyes Barrios was deported to El Salvador with no notice to counsel or family. It was not until March 18, 2025 that counsel was able to reach an ICE official and learn that he had in fact been deported. 6. Mr. Reyes Barrios was/is a professional soccer player in Venezuela. He has never been arrested or charged with a crime. He has a steady employment record as a soccer player, as well as a soccer coach for children and youth. 7. Initially, Mr. Reyes Barrios was placed in maximum security at Otay Mesa and accused of being a Tren de Aragua gang member. The accusation is based on two things. First, he has a tattoo on his arm of a crown sitting atop a soccer ball with a rosary and the word "Dies." OHS alleges that this tattoo is proof of gang membership. In reality, he chose this tattoo, because it is similar to the logo for his favorite soccer team Real Madrid. See logo below. [pictures of the tattoo and the pictures of the logo]. 8. Second, OHS reviewed his social media posts and found a photo of Mr. Reyes Barrios making a hand gesture that they allege is proof of gang membership. 9. After submitting a police clearance from Venezuela indicating no criminal record, multiple employment letters, a declaration from the tattoo artist who rendered the tattoo, and various online images showing similar soccer ball/crown tattoos and explaining the meaning of the hand gesture, Mr. Reyes Barrios was transferred out of maximum security. 10. Nevertheless on March 10th or 11th, he was transferred from Otay Mesa to Texas without notice. Then, on March 15, 2025, he was deported to El Salvador. Counsel and family have lost all contact with him have no information regarding his whereabouts or condition.
