## Pentagon lends DHS a heat ray for border testing

The Pentagon authorized the Department of Homeland Security to [test a military heat ray and develop tactics](https://cnnespanol.cnn.com/2026/10/21/eeuu/pentagono-dhs-arma-rayos-calor-frontera-trax) for possible use at the southern border, under a memo Defense Secretary Pete Hegseth signed in September. The weapon, called the Active Denial System, [fires an invisible beam that causes a burning sensation](https://www.scrippsnews.com/us-news/pentagon-grants-dhs-permission-to-test-heat-ray-weapon-for-potential-use-at-border). The memo [lends DHS one system for seven months](https://www.semana.com/mundo/noticias-estados-unidos/articulo/la-nueva-arma-de-trump-pentagono-aprueba-el-ensayo-de-mecanismo-con-rayos-de-calor-para-su-posible-uso-en-la-frontera/202620/), [bars Pentagon personnel from operating it](https://lahora.gt/internacionales/dguzman/2026/10/21/pentagono-autoriza-al-dhs-a-probar-un-arma-de-rayos-de-calor-en-la-frontera-con-mexico/) and makes DHS solely responsible for how it is used. [The leaked memo first surfaced Oct. 8](https://www.jimacosta.com/p/exclusive-leaked-dod-memo-reveals). [CNN, Scripps News, Semana, La Hora, Jim Acosta]

The idea has circulated at the border for years. [The El Centro sector evaluated the system](https://lahora.gt/internacionales/dguzman/2026/10/21/pentagono-autoriza-al-dhs-a-probar-un-arma-de-rayos-de-calor-en-la-frontera-con-mexico/) when Rodney Scott, now CBP commissioner, led it, weighing whether it could push people out of a nearby river; a former CBP official warned, “you don’t want them to go in and drown.” In 2018, then-Homeland Security Secretary Kirstjen Nielsen [rejected using it against migrants](https://www.scrippsnews.com/us-news/pentagon-grants-dhs-permission-to-test-heat-ray-weapon-for-potential-use-at-border). CBP said it “is continually evaluating new technologies.” [La Hora, Scripps News]

Zooming out, a Just Security analysis of [DHS’s artificial-intelligence inventory](https://www.justsecurity.org/159720/dhs-ai-inventory-limits-federal-ai-transparency-law/) finds the department does not label ICE’s ELITE app — which uses AI to pull likely migrant addresses from government records, including Health and Human Services data — as “high-impact,” letting it skip required testing and auditing. ICE and CBP list 25 high-impact uses, including the Mobile Fortify facial-recognition app, but disclose little about their safeguards. [Just Security]

## Voting cases expand beyond the courtroom

Federal prosecutors [charged 28 California green-card holders with voting-related crimes](https://www.justice.gov/opa/pr/justice-department-charges-28-foreign-nationals-california-election-crimes) and arrested 11 on Oct. 19. [Prosecutors allege 22 voted](https://calmatters.org/calmatters-en-espanol/2026/10/california-demanda-nociudadanos-votantes/) in at least one election; five only registered. Elsewhere, [armed Homeland Security agents have been knocking on doors](https://www.cbsnews.com/news/federal-agents-seek-noncitizen-voters/) in at least six states to ask residents about their immigration status and whether they voted. The Justice Department counts 156 people charged with voting-fraud offenses since the administration began, out of 227 million registered voters. [U.S. Department of Justice, CalMatters, CBS News]

In a separate civil case, the federal government [asked a judge to force California to set aside up to 20,000 mail ballots](https://calmatters.org/calmatters-en-espanol/2026/10/california-demanda-nociudadanos-votantes/) it says may have gone to noncitizens. In [an Oct. 20 filing](https://www.documentcloud.org/documents/28825643-10-20-2026-pltfs-tro-opp/), Attorney General Rob Bonta argued the suit borders on the absurd. Los Angeles County officials who [reviewed a sample of 200 names](https://calmatters.org/calmatters-en-espanol/2026/10/california-demanda-nociudadanos-votantes/) said many appear to be citizens and most had not voted. [CalMatters, Court filing]

## 287(g) Watch shows who’s running for sheriff

With Election Day two weeks away, [287(g) Watch now shows the sheriff’s race](https://recoveredfactory.net/en/287g-watch-redesign) on the page of every agency in a county that elects its sheriff this year — who’s running, their party and whether a candidate signed the office’s 287(g) agreement with ICE. Sheriffs are elected in nearly every state and usually decide whether their deputies help enforce federal immigration law, which makes the vote for sheriff one of the few direct ways voters can weigh in on local collaboration with ICE. We found 242 sheriff’s offices with agreements to work with ICE that have a sheriff’s race on the ballot. [287(g) Watch]

The network keeps growing: the site tracks 2,231 agencies in 40 states that had signed on to work with ICE as of Oct. 16, including [146 in Pennsylvania](https://www.pennlive.com/news/2026/10/ice-partnerships-with-pa-law-enforcement-have-exploded-this-year-see-which-agencies-have-agreements.html), while authorized North Carolina highway patrol officers [may ask motorists about their immigration status](https://enlacelatinonc.org/patrulla-de-carreteras-de-carolina-del-norte-preguntar-estatus-migratorio/). [287(g) Watch, PennLive, Enlace Latino NC]

## Senators challenge government lawyers for children

Six senators [asked Health and Human Services Secretary Robert F. Kennedy Jr. to reverse a plan for department attorneys to represent unaccompanied children in immigration court](https://www.wyden.senate.gov/news/press-releases/wyden-calls-on-hhs-secretary-to-reverse-plans-for-trump-administration-lawyers-to-represent-unaccompanied-children-in-immigration-court), arguing the department cannot be the children’s lawyer while it holds them in custody, decides where they live and shares information with immigration enforcement. “The immigration judge works for the Trump Administration. So does the prosecutor. Under your plan, so would the child’s lawyer,” they wrote, citing a 2008 law that requires the department to seek independent pro bono counsel. [Sen. Ron Wyden]

In San Antonio, [183 unaccompanied children in federal shelter custody had open immigration cases as of Aug. 31, out of 1,523 nationwide](https://www.tpr.org/border-immigration/2026-10-21/children-in-san-antonio-face-immigration-court-alone-as-faster-deportations-loom), according to [bklg.org's analysis of court records](https://bklg.org/blog/newly-detained-kids-sent-to-texas/). The federal contract that funded community legal providers for those children expired July 31, and more of them are now facing hearings without lawyers. [Texas Public Radio, bklg.org]

## New country assessments could shape asylum decisions

State Department assessments sent to asylum officers [describe parts of Mexico and Central America as safer than some U.S. cities](https://cnnespanol.cnn.com/2026/10/21/eeuu/solicitudes-asilo-minimiza-peligros-america-latina-trax), even as public travel guidance warns Americans about dangers in the region. The documents [compare violent crime there favorably with Baltimore and Houston](https://www.kten.com/news/politics/exclusive-state-department-warns-americans-about-latin-america-privately-it-tells-asylum-officers-a-different/article_6e09cce3-3a7d-560b-8f98-cd21f1a54159.html). Those assessments [could affect whether applicants are considered able to relocate safely](https://www.prensalibre.com/guatemala/migrantes/ee-uu-compara-la-violencia-en-centroamerica-con-la-de-sus-ciudades-que-implica-para-quienes-piden-asilo/) within their own countries. [CNN, Prensa Libre]

They land on a system already denying most claims: TRAC’s [June 2026 asylum-decision data](https://tracreports.org/phptools/immigration/asylum/) show 13,994 denials, 812 grants of asylum and 439 grants of other relief. Among cases ending in an asylum grant or denial, 94.5% were denied. [TRAC]
