Montana
Entries whose effect landed somewhere in Montana (MT) — a city, a county, a campus, a detention facility — whichever government acted. Federal conduct inside Montana counts here.
This is not the same set as Montana's jurisdiction page, which records the 21 entries where Montana's own government was the acting authority, wherever those events happened. The two overlap and neither contains the other: place and power are separate facts, and statewide acts appear there and not here.

ICE detained as many as 100 people during week-long enforcement operations in Gallatin County, Montana
Over the week of roughly June 25 through July 2, 2026, U.S. Immigration and Customs Enforcement conducted a series of enforcement operations across Gallatin County, Montana, detaining an estimated several dozen to more than 100 people, according to local immigrant-resource organizations. Community members reported people being pulled over in their vehicles and detained along with other occupants, including bystanders in the same vehicle, and agents knocking on doors in search of specific individuals. The largest single-day wave, more than 80 detentions, was reported on Wednesday, July 1.

CBP arrested a Billings parent and his 9-year-old child without a warrant and held them at the Havre Border Patrol Station
U.S. Customs and Border Protection agents arrested Adrián Espinoza De La Cruz, a four-year Billings resident, and his 9-year-old child on Aug. 11, 2026 without a judicial warrant and took them to the Havre Border Patrol Station in northern Montana, where both remained in custody nine days later. Attorneys with Upper Seven Law petitioned the U.S. District Court for the District of Montana for their release, arguing the Havre station is not built for long-term detention and that a detained minor is entitled to specific protections the government has not shown it is meeting. The U.S. Attorney's Office acknowledged in a court filing that agents made the arrest without a warrant and without evidence the two posed an escape risk, and argued that releasing them would nonetheless not be appropriate.

Yellowstone County, Montana retroactively moved ballot-initiative deadline a month earlier at data-center developer's urging, killing citizen petition
On August 4, 2026, Yellowstone County, Montana's attorney's office announced that the signature deadline for a citizen ballot initiative regulating data centers had actually passed a month earlier, reversing the August 12 deadline the county's own election department had given organizers in June. The county said it adopted the new July 13 deadline after data-center developer Quantica Infrastructure's attorney flagged a different statute to the county attorney on July 30.
