Nashville Noticias staffer Estefany Rodríguez was detained by ICE in South Nashville on Wednesday morning. There was no warrant for her arrest. Her attorneys have filed an emergency petition in federal court seeking a writ of habeas corpus, or an immediate review of whether or not her detention is legal. 

Rodríguez, who was in the car with her husband — a U.S. citizen — has been following all the legal steps to citizenship. In her job, Rodríguez has reported several stories that hold ICE accountable, and it’s unclear whether her detention was retaliation. As of Thursday afternoon, she was in Alabama en route to an ICE processing center in Louisiana.

Something I don’t think can be emphasized enough is how fast ICE is shipping the people they detain off to another state. “Move fast and break things” but for people in potentially life or death situations. nashvillebanner.com/2026/03/05/j...

Kristi Noem Didn’t Give a Sh*t About ‘the Details’ Such as a woman who was here legally and helped the homeless—but was then deported anyway.

NEW: Here's the story of a woman deported by Kristi Noem. Legally in the United States (as a DACA recipient), she is the mother of a U.S. citizen and was working to help the homeless—but when she went for an appointment to get a green card, she was deported.

Far more than just an office building, NSF NCAR Mesa Lab is an iconic and purpose-built facility designed specifically for the study of atmospheric science. Its position at the physical interface of the Rocky Mountain foothills and the Great Plains is a deliberate reflection of its mission, serving as a visible symbol—in an iconically American setting—of the federal government's enduring commitment to science in service of society. For many in the field, including myself, the Mesa Lab holds singular importance as a focal gathering point for the global atmospheric science community.

I just submitted my letter to NSF responding to its proposal to dismantle the National Center for Atmospheric Research (NCAR). I argue that doing so would be an astonishing and avoidable misstep, and that federal support for the institution should in fact be *increased.* [1/4]
